kbuild: doc: remove outdated description of the limitation on -I usage
Kbuild used to manipulate header search paths, enforcing the odd
limitation of "no space after -I".
Commit cdd750bfb1f7 ("kbuild: remove 'addtree' and 'flags' magic for
header search paths") stopped doing that. This limitation no longer
exists. Instead, you need to accurately specify the header search path.
(In this case, $(src)/include)

kbuild: doc: update the description about Kbuild/Makefile split
The phrase "In newer versions of the kernel" was added 14 years ago, by
commit efdf02cf0651 ("Documentation/kbuild: major edit of modules.txt
sections 1-4"). This feature is no longer new, so remove it and update
the paragraph.
Example 3 was written 20 years ago [1]. There is no need to note about
backward compatibility with such an old build system. Remove Example 3
entirely.

bcachefs changes for 6.12-rc1
rcu_pending, btree key cache rework: this solves lock contenting in the key cache, eliminating the biggest source of the srcu lock hold time warnings, and drastically improving performance on some metadata heavy workloads - on multithreaded creates we're now 3-4x faster than xfs. We're now using an rhashtable instead of the system inode hash table; this is another significant performance improvement on multithreaded metadata workloads, eliminating more lock contention. for_each_btree_key_in_subvolume_upto(): new helper for iterating over keys within a specific subvolume, eliminating a lot of open coded "subvolume_get_snapshot()" and also fixing another source of srcu lock time warnings, by running each loop iteration in its own transaction (as the existing for_each_btree_key() does). More work on btree_trans locking asserts; we now assert that we don't hold btree node locks when trans->locked is false, which is important because we don't use lockdep for tracking individual btree node locks. Some cleanups and improvements in the bset.c btree node lookup code, from Alan. Rework of btree node pinning, which we use in backpointers fsck. The old hacky implementation, where the shrinker just skipped over nodes in the pinned range, was causing OOMs; instead we now use another shrinker with a much higher seeks number for pinned nodes. Rebalance now uses BCH_WRITE_ONLY_SPECIFIED_DEVS; this fixes an issue where rebalance would sometimes fall back to allocating from the full filesystem, which is not what we want when it's trying to move data to a specific target. Use __GFP_ACCOUNT, GFP_RECLAIMABLE for btree node, key cache allocations. Idmap mounts are now supported - Hongbo. Rename whiteouts are now supported - Hongbo. Erasure coding can now handle devices being marked as failed, or forcibly removed. We still need the evacuate path for erasure coding, but it's getting very close to ready for people to start using. Status, and when will we be taking off experimental: ---------------------------------------------------- Going by critical, user facing bugs getting found and fixed, we're nearly there. There are a couple key items that need to be finished before we can take off the experimental label: - The end-user experience is still pretty painful when the root filesystem needs a fsck; we need some form of limited self healing so that necessary repair gets run automatically. Errors (by type) are recorded in the superblock, so what we need to do next is convert remaining inconsistent() errors to fsck() errors (so that all runtime inconsistencies are logged in the superblock), and we need to go through the list of fsck errors and classify them by which fsck passes are needed to repair them. - We need comprehensive torture testing for all our repair paths, to shake out remaining bugs there. Thomas has been working on the tooling for this, so this is coming soonish. Slightly less critical items: - We need to improve the end-user experience for degraded mounts: right now, a degraded root filesystem means dropping to an initramfs shell or somehow inputting mount options manually (we don't want to allow degraded mounts without some form of user input, except on unattended servers) - we need the mount helper to prompt the user to allow mounting degraded, and make sure this works with systemd. - Scalabiity: we have users running 100TB+ filesystems, and that's effectively the limit right now due to fsck times. We have some reworks in the pipeline to address this, we're aiming to make petabyte sized filesystems practical. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKnAFLkS8Qha+jvQrE6szbY3KbnYFAmbvHQoACgkQE6szbY3K bnYfAw/+IXQ43/O+Jzs0MLD7pKZnrlbHiX9FqYLazD40vWvkyRTQOwgTn8pVNhq3 4YWmtuZyqh036YC+bGqYFOhz20YetS5UdgbClpwmc99JJ6xsY+Z1mdpYfz5oq1Dw /pBX5iYb3rAt8UbQoZ8lcWM+GpT3GKJVgJuiLB2gRp9gATFesuh+0qU42oIVVVU5 4y3VhDBUmRk4XqEnk8hr7EIDMW0wWP3aptxYMZzeUPW0x1cEQ+FWrJo5D6lXv2KK dKv3MogvA0FFNi/eNexclPiu2pXtI7vrxT7umsxAICHLt41rWpV5ttE6io3bC4ZN qvwF9w2CpmKPKchFru9PO+QrWHVR7e6bphwf3TzyoKZ7tTn42f1RQlub7gBzI3bz ai5ZwGRIvpUoPVBj+CO+Ipog81uUb23Ma+gXg1akEFBOAb+o7I3KOOSBh5l+0cHj 3Ov1n0TLcsoO2cqoqfsV2QubW9YcWEZ76g5mKwQnUn8Cs6Fp0wWaIyK9aNkIAxcr tNDPGtH1gKitxUvju5i/LyI7y1UoeFvqJFee0VsU6QnixHn1ySzhePsJt6UEnIJT Ia3C96Igqu2mV9FxhfGHj/qi7TGjqqkZHa8+B610cDpgf15cx7Ps2DYjkuQMFCqZ Q3Q1o5De9roRq5xF2hLiYJCbzJKqd5ichFsBtLQuX572ICxbICg= =oVCy -----END PGP SIGNATURE----- Merge tag 'bcachefs-2024-09-21' of git://evilpiepirate.org/bcachefs Pull bcachefs updates from Kent Overstreet: - rcu_pending, btree key cache rework: this solves lock contenting in the key cache, eliminating the biggest source of the srcu lock hold time warnings, and drastically improving performance on some metadata heavy workloads - on multithreaded creates we're now 3-4x faster than xfs. - We're now using an rhashtable instead of the system inode hash table; this is another significant performance improvement on multithreaded metadata workloads, eliminating more lock contention. - for_each_btree_key_in_subvolume_upto(): new helper for iterating over keys within a specific subvolume, eliminating a lot of open coded "subvolume_get_snapshot()" and also fixing another source of srcu lock time warnings, by running each loop iteration in its own transaction (as the existing for_each_btree_key() does). - More work on btree_trans locking asserts; we now assert that we don't hold btree node locks when trans->locked is false, which is important because we don't use lockdep for tracking individual btree node locks. - Some cleanups and improvements in the bset.c btree node lookup code, from Alan. - Rework of btree node pinning, which we use in backpointers fsck.

sched_ext: Provide a sysfs enable_seq counter
As discussed during the distro-centric session within the sched_ext Microconference at LPC 2024, introduce a sequence counter that is incremented every time a BPF scheduler is loaded. This feature can help distributions in diagnosing potential performance regressions by identifying systems where users are running (or have ran) custom BPF schedulers. Example: arighi@virtme-ng~> cat /sys/kernel/sched_ext/enable_seq 0 arighi@virtme-ng~> sudo scx_simple local=1 global=0 ^CEXIT: unregistered from user space arighi@virtme-ng~> cat /sys/kernel/sched_ext/enable_seq 1 In this way user-space tools (such as Ubuntu's apport and similar) are able to gather and include this information in bug reports.

ring-buffer: Updates for v6.12:
- Merged v6.11-rc3 into trace/ring-buffer/core
The v6.10 ring buffer pull request was not made due to Mathieu Desnoyers
making a comment to the pull request. Mathieu and I resolved it on IRC,
but we did not let Linus know that it was resolved. Linus did not do the
pull thinking it still had some unresolved issues.
The ring buffer work for 6.12 was dependent on both this pull request as
well as the reserve_mem kernel command line option that was going upstream
through the memory management tree. The ring buffer repo was being used by
others so it could not be rebased. In order to continue the work, the
v6.11-rc3 branch was pulled in to get access to the reserve_mem work.
This has the 6.11 pull request that did not make it into 6.11, which was:
tracing/ring-buffer: Have persistent buffer across reboots
This allows for the tracing instance ring buffer to stay persistent across
reboots. The way this is done is by adding to the kernel command line:
trace_instance=boot_map@0x285400000:12M
This will reserve 12 megabytes at the address 0x285400000, and then map
the tracing instance "boot_map" ring buffer to that memory. This will
appear as a normal instance in the tracefs system:
/sys/kernel/tracing/instances/boot_map
A user could enable tracing in that instance, and on reboot or kernel
crash, if the memory is not wiped by the firmware, it will recreate the
trace in that instance. For example, if one was debugging a shutdown of a
kernel reboot:
# cd /sys/kernel/tracing
# echo function > instances/boot_map/current_tracer
# reboot
[..]
# cd /sys/kernel/tracing
# tail instances/boot_map/trace

On reboot, the buffer is examined to make sure it is valid. The validation
check even steps through every event to make sure the meta data of the
event is correct. If any test fails, it will simply reset the buffer, and
the buffer will be empty on boot.
The new changes for 6.12 are:
- Allow the tracing persistent boot buffer to use the "reserve_mem" option
Instead of having the admin find a physical address to store the persistent
buffer, which can be very tedious if they have to administrate several
different machines, allow them to use the "reserve_mem" option that will
find a location for them. It is not as reliable because of KASLR, as the
loading of the kernel in different locations can cause the memory
allocated to be inconsistent. Booting with "nokaslr" can make reserve_mem
more reliable.
- Have function graph tracer handle offsets from a previous boot.
The ring buffer output from a previous boot may have different addresses
due to kaslr. Have the function graph tracer handle these by using the
delta from the previous boot to the new boot address space.
- Only reset the saved meta offset when the buffer is started or reset
In the persistent memory meta data, it holds the previous address space
information, so that it can calculate the delta to have function tracing
work. But this gets updated after being read to hold the new address
space. But if the buffer isn't used for that boot, on reboot, the delta is
now calculated from the previous boot and not the boot that holds the data
in the ring buffer. This causes the functions not to be shown. Do not save
the address space information of the current kernel until it is being
recorded.
- Add a magic variable to test the valid meta data
Add a magic variable in the meta data that can also be used for
validation. The validator of the previous buffer doesn't need this magic
data, but it can be used if the meta data is changed by a new kernel, which
may have the same format that passes the validator but is used
differently. This magic number can also be used as a "versioning" of the
meta data.
- Align user space mapped ring buffer sub buffers to improve TLB entries
Linus mentioned that the mapped ring buffer sub buffers were misaligned
between the meta page and the sub-buffers, so that if the sub-buffers were
bigger than PAGE_SIZE, it wouldn't allow the TLB to use bigger entries.
- Add new kernel command line "traceoff" to disable tracing on boot for instances
If tracing is enabled for a boot instance, there needs a way to be able to
disable it on boot so that new events do not get entered into the ring
buffer and be mixed with events from a previous boot, as that can be
confusing.
- Allow trace_printk() to go to other instances
Currently, trace_printk() can only go to the top level instance. When
debugging with a persistent buffer, it is really useful to be able to add
trace_printk() to go to that buffer, so that you have access to them after
a crash.
- Do not use "bin_printk()" for traces to a boot instance
The bin_printk() saves only a pointer to the printk format in the ring
buffer, as the reader of the buffer can still have access to it. But this
is not the case if the buffer is from a previous boot. If the
trace_printk() is going to a "persistent" buffer, it will use the slower
version that writes the printk format into the buffer.
- Add command line option to allow trace_printk() to go to an instance
Allow the kernel command line to define which instance the trace_printk()
goes to, instead of forcing the admin to set it for every boot via the
tracefs options.
- Start a document that explains how to use tracefs to debug the kernel
- Add some more kernel selftests to test user mapped ring buffer

the ring buffer and be mixed with events from a previous boot, as
that can be confusing.
- Allow trace_printk() to go to other instances
Currently, trace_printk() can only go to the top level instance. When
debugging with a persistent buffer, it is really useful to be able to
add trace_printk() to go to that buffer, so that you have access to
them after a crash.
- Do not use "bin_printk()" for traces to a boot instance
The bin_printk() saves only a pointer to the printk format in the
ring buffer, as the reader of the buffer can still have access to it.
But this is not the case if the buffer is from a previous boot. If
the trace_printk() is going to a "persistent" buffer, it will use the
slower version that writes the printk format into the buffer.
- Add command line option to allow trace_printk() to go to an instance
Allow the kernel command line to define which instance the
trace_printk() goes to, instead of forcing the admin to set it for
every boot via the tracefs options.
- Start a document that explains how to use tracefs to debug the kernel
- Add some more kernel selftests to test user mapped ring buffer

sched_ext: Initial pull request for v6.12
This is the initial pull request of sched_ext. The v7 patchset
(https://lkml.kernel.org/r/20240618212056.2833381-1-tj@kernel.org) is
applied on top of tip/sched/core + bpf/master as of Jun 18th.
tip/sched/core 793a62823d1c ("sched/core: Drop spinlocks on contention iff kernel is preempti
ble")
bpf/master f6afdaf72af7 ("Merge branch 'bpf-support-resilient-split-btf'")
Since then, the following pulls were made:
- v6.11-rc1 is pulled to keep up with the mainline.
- tip/sched/core was pulled several times:
- 7b9f6c864a34, 0df340ceae2e, 5ac998574f93, 0b1777f0fa04: To resolve
conflicts. See each commit for details on conflicts and their
resolutions.
- d7b01aef9dbd: To receive fd03c5b85855 ("sched: Rework pick_next_task()")
and related commits. @prev in added to sched_class->put_prev_task() and
put_prev_task() is reordered after ->pick_task(), which makes
sched_class->switch_class() unnecessary. The follow-up commits update
sched_ext accordingly and drop sched_class->switch_class().
- bpf/master was pulled to receive baebe9aaba1e ("bpf: allow passing struct
bpf_iter_<type> as kfunc arguments") and related changes in preparation
for the DSQ iterator patchset
To obtain the net sched_ext changes, diff against:
git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext.git for-6.12-base
which is the merge of:
tip/sched/core bc9057da1a22 ("sched/cpufreq: Use NSEC_PER_MSEC for deadline task")
bpf/master 2ad6d23f465 ("selftests/bpf: Do not update vmlinux.h unnecessarily")
Since the v7 patchset, the following changes were made:
- cpuperf support which was a part of the v6 patchset was posted separately
and then applied after reviews.
- cgroup support which was a part of the v6 patchset was posted seprately,
iterated and then applied.
- Improve integration with sched core.
- Double locking usage in migration paths dropped. Depend on
TASK_ON_RQ_MIGRATING synchronization instead.
- The BPF scheduler couldn't directly dispatch to the local DSQ of another
CPU using a SCX_DSQ_LOCAL_ON verdict. This caused difficulties around
handling non-wakeup enqueues. Updated so that SCX_DSQ_LOCAL_ON can be used
in the enqueue path too.
- DSQ iterator which was a part of the v6 patchset was posted separately.
The iterator itself was applied after a couple revisions. The associated
selective consumption kfunc can use further improvements and is still
being worked on.
- scx_bpf_dispatch[_vtime]_from_dsq() added to increase flexibility. A task
can now be transferred between two DSQs from almost any context. This
involved significant refactoring of migration code.
- Various fixes and improvements.
As the branch is based on top of tip/sched/core + bpf/master, please merge
after both are applied.

Pull sched_ext support from Tejun Heo:
"This implements a new scheduler class called ‘ext_sched_class’, or
sched_ext, which allows scheduling policies to be implemented as BPF
programs.
The goals of this are:
- Ease of experimentation and exploration: Enabling rapid iteration
of new scheduling policies.
- Customization: Building application-specific schedulers which
implement policies that are not applicable to general-purpose
schedulers.
- Rapid scheduler deployments: Non-disruptive swap outs of scheduling
policies in production environments"

for the latest series:

Merge tag 'bpf-next-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next
Pull bpf updates from Alexei Starovoitov:
- Introduce '__attribute__((bpf_fastcall))' for helpers and kfuncs with
corresponding support in LLVM.
It is similar to existing 'no_caller_saved_registers' attribute in
GCC/LLVM with a provision for backward compatibility. It allows
compilers generate more efficient BPF code assuming the verifier or
JITs will inline or partially inline a helper/kfunc with such
attribute. bpf_cast_to_kern_ctx, bpf_rdonly_cast,
bpf_get_smp_processor_id are the first set of such helpers.
- Harden and extend ELF build ID parsing logic.
When called from sleepable context the relevants parts of ELF file
will be read to find and fetch .note.gnu.build-id information. Also
harden the logic to avoid TOCTOU, overflow, out-of-bounds problems.
- Improvements and fixes for sched-ext:
- Allow passing BPF iterators as kfunc arguments
- Make the pointer returned from iter_next method trusted
- Fix x86 JIT convergence issue due to growing/shrinking conditional
jumps in variable length encoding
- BPF_LSM related:
- Introduce few VFS kfuncs and consolidate them in
fs/bpf_fs_kfuncs.c
- Enforce correct range of return values from certain LSM hooks
- Disallow attaching to other LSM hooks
- Prerequisite work for upcoming Qdisc in BPF:
- Allow kptrs in program provided structs
- Support for gen_epilogue in verifier_ops
- Important fixes:
- Fix uprobe multi pid filter check
- Fix bpf_strtol and bpf_strtoul helpers
- Track equal scalars history on per-instruction level
- Fix tailcall hierarchy on x86 and arm64
- Fix signed division overflow to prevent INT_MIN/-1 trap on x86
- Fix get kernel stack in BPF progs attached to tracepoint:syscall
- Selftests:
- Add uprobe bench/stress tool
- Generate file dependencies to drastically improve re-build time
- Match JIT-ed and BPF asm with __xlated/__jited keywords
- Convert older tests to test_progs framework
- Add support for RISC-V
- Few fixes when BPF programs are compiled with GCC-BPF backend
(support for GCC-BPF in BPF CI is ongoing in parallel)
- Add traffic monitor
- Enable cross compile and musl libc

ALong with the usual shower of singleton patches, notable patch series in
this pull request are:
"Align kvrealloc() with krealloc()" from Danilo Krummrich. Adds
consistency to the APIs and behaviour of these two core allocation
functions. This also simplifies/enables Rustification.
"Some cleanups for shmem" from Baolin Wang. No functional changes - mode
code reuse, better function naming, logic simplifications.
"mm: some small page fault cleanups" from Josef Bacik. No functional
changes - code cleanups only.
"Various memory tiering fixes" from Zi Yan. A small fix and a little
cleanup.
"mm/swap: remove boilerplate" from Yu Zhao. Code cleanups and
simplifications and .text shrinkage.
"Kernel stack usage histogram" from Pasha Tatashin and Shakeel Butt. This
is a feature, it adds new feilds to /proc/vmstat such as
$ grep kstack /proc/vmstat
kstack_1k 3
kstack_2k 188
kstack_4k 11391
kstack_8k 243
kstack_16k 0
which tells us that 11391 processes used 4k of stack while none at all
used 16k. Useful for some system tuning things, but partivularly useful
for "the dynamic kernel stack project".
"kmemleak: support for percpu memory leak detect" from Pavel Tikhomirov.
Teaches kmemleak to detect leaksage of percpu memory.
"mm: memcg: page counters optimizations" from Roman Gushchin. "3
independent small optimizations of page counters".
"mm: split PTE/PMD PT table Kconfig cleanups+clarifications" from David
Hildenbrand. Improves PTE/PMD splitlock detection, makes powerpc/8xx work
correctly by design rather than by accident.
"mm: remove arch_make_page_accessible()" from David Hildenbrand. Some
folio conversions which make arch_make_page_accessible() unneeded.
"mm, memcg: cg2 memory{.swap,}.peak write handlers" fro David Finkel.
Cleans up and fixes our handling of the resetting of the cgroup/process
peak-memory-use detector.
"Make core VMA operations internal and testable" from Lorenzo Stoakes.
Rationalizaion and encapsulation of the VMA manipulation APIs. With a
view to better enable testing of the VMA functions, even from a
userspace-only harness.

The DesignWare and the Renesas I2C drivers have received most of
the changes in this pull request.
The first has has undergone through a series of cleanups that
have been sent to the mailing list a year ago for the first time
and finally get merged in this pull request. They are many, from
typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move
inline functions to librarieas) and many others.
Besides that, all the DesignWare Kconfig options have been
grouped under the I2C_DESIGNWARE_CORE and this required some
adaptation in many of the kernel configuration files for
different arm and mips boards.
Follows the list of the rest of the changes grouped by type of
change.
Cleanups
--------
The Qualcomm Geni platform improves the exit path in the runtime
resume function.
The Intel LJCA driver loses "target_addr" parameter in
ljca_i2c_stop() because it was unused.
The MediaTek controller intializes the restart_flag in the
transfer function using the ternary conditional operator ("? :")
instead of initializing it in different parts.
Constified a few global data structures in the virtio driver.
The Renesas driver simplifies the bus speed handling in the init
function making it more readable.
Improved an if/else statement in probe function of the Renesas
R-Car driver.
The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead
of SET_RUNTIME_PM_OPS().
Still in the iMX/MXC driver a comma ',' has been replaced by a
semicolon ';', while in different drivers the ',' has been
removed from the '{ }' delimiters.
Finally three devm_clk_get_enabled() have been used to simplify
the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2,
Ingenic and MPC drivers.
Refactors
---------
The Nuvoton fixes a potential out of boundary array access. This
is not a bug fix because the issue could never occur due to
hardware not having the properties listed in the array. The
change makes the driver more future proof and, at the same time,
silences code analyzers.
Improvements
------------
The Renesas I2C (riic) driver undergoes several patches improving
the runtime power management handling.
The Intel i801 driver uses a more descriptive adapter's name to
show the presence of the IDF feature.
In the Intel Denverton (ismt) adapter the pending transactions
are killed when irq's can't complete their handling, triggering a
timeout. This could have been considered as a bug fix, but
because, standing to Vasily, it's very sporadic, I preferred
considering the patch rather as an improvement.
New Feature
-----------
The Renesas I2C (riic) driver now supports the fast mode plus.
New support
-----------
Added support for:
- Renesas R9A08G045
- Rockchip RK3576
- KEBA I2C
- Theobroma Systems Mule Multiplexer.
The Keba comes with a new driver, i2c-keba.c.
The Mule is an i2c multiplexer and it also comes with a new
driver, mux/i2c-mux-mule.c.
Core patch
----------
This pull request includes also a patch in the I2C framework, in
i2c-core-base.c where the runtime PM functions have been replaced
in order to allow to be accessed during the device add.
Devicetree
----------
Some cleanups in the devicetree, as well. nVidia and Qualcomm
bindings improve their "if:then:" blocks. While the aspeed
binding loses the "multi-master" property because it was
redundant.
The i2c-sprd binding has been converted to YAML.

There has been efforts over the last 16 years to enable enable Large Block Sizes (LBS), that is block sizes in filesystems where bs > page size. Through these efforts we have learned that one of the main blockers to supporting bs > ps in filesystems has been a way to allocate pages that are at least the filesystem block size on the page cache where bs > ps. Thanks to various previous efforts it is possible to support bs > ps in XFS with only a few changes in XFS itself. Most changes are to the page cache to support minimum order folio support for the target block size on the filesystem. A motivation for Large Block Sizes today is to support high-capacity (large amount of Terabytes) QLC SSDs where the internal Indirection Unit (IU) are typically greater than 4k to help reduce DRAM and so in turn cost and space. In practice this then allows different architectures to use a base page size of 4k while still enabling support for block sizes aligned to the larger IUs by relying on high order folios on the page cache when needed. It also allows to take advantage of the drive's support for atomics larger than 4k with buffered IO support in Linux. As described this year at LSFMM, supporting large atomics greater than 4k enables databases to remove the need to rely on their own journaling, so they can disable double buffered writes, which is a feature different cloud providers are already enabling through custom storage solutions" * tag 'vfs-6.12.blocksize' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs: (22 commits) Documentation: iomap: fix a typo iomap: remove the iomap_file_buffered_write_punch_delalloc return value iomap: pass the iomap to the punch callback iomap: pass flags to iomap_file_buffered_write_punch_delalloc iomap: improve shared block detection in iomap_unshare_iter iomap: handle a post-direct I/O invalidate race in iomap_write_delalloc_release docs:filesystems: fix spelling and grammar mistakes in iomap design page filemap: fix htmldoc warning for mapping_align_index() iomap: make zero range flush conditional on unwritten mappings iomap: fix handling of dirty folios over unwritten extents iomap: add a private argument for iomap_file_buffered_write iomap: remove set_memor_ro() on zero page xfs: enable block size larger than page size support xfs: make the calculation generic in xfs_sb_validate_fsb_count() xfs: expose block size in stat xfs: use kvmalloc for xattr buffers iomap: fix iomap_dio_zero() for fs bs > system page size filemap: cap PTE range to be created to allowed zero fill in folio_map_range() mm: split a folio in minimum folio order chunks readahead: allocate folios with mapping_min_order in readahead ... |

kbuild: generate offset range data for builtin modules
Create file module.builtin.ranges that can be used to find where
built-in modules are located by their addresses. This will be useful for
tracing tools to find what functions are for various built-in modules.
The offset range data for builtin modules is generated using:
- modules.builtin: associates object files with module names
- vmlinux.map: provides load order of sections and offset of first member
per section
- vmlinux.o.map: provides offset of object file content per section
- .*.cmd: build cmd file with KBUILD_MODFILE
The generated data will look like:
.text 00000000-00000000 = _text
.text 0000baf0-0000cb10 amd_uncore
.text 0009bd10-0009c8e0 iosf_mbi
...
.text 00b9f080-00ba011a intel_skl_int3472_discrete
.text 00ba0120-00ba03c0 intel_skl_int3472_discrete intel_skl_int3472_tps68470
.text 00ba03c0-00ba08d6 intel_skl_int3472_tps68470
...
.data 00000000-00000000 = _sdata
.data 0000f020-0000f680 amd_uncore
For each ELF section, it lists the offset of the first symbol. This can
be used to determine the base address of the section at runtime.
Next, it lists (in strict ascending order) offset ranges in that section
that cover the symbols of one or more builtin modules. Multiple ranges
can apply to a single module, and ranges can be shared between modules.
The CONFIG_BUILTIN_MODULE_RANGES option controls whether offset range data
is generated for kernel modules that are built into the kernel image.
How it works:
1. The modules.builtin file is parsed to obtain a list of built-in
module names and their associated object names (the .ko file that
the module would be in if it were a loadable module, hereafter
referred to as <kmodfile>). This object name can be used to
identify objects in the kernel compile because any C or assembler
code that ends up into a built-in module will have the option
-DKBUILD_MODFILE=<kmodfile> present in its build command, and those
can be found in the .<obj>.cmd file in the kernel build tree.
If an object is part of multiple modules, they will all be listed
in the KBUILD_MODFILE option argument.
This allows us to conclusively determine whether an object in the
kernel build belong to any modules, and which.
2. The vmlinux.map is parsed next to determine the base address of each
top level section so that all addresses into the section can be
turned into offsets. This makes it possible to handle sections
getting loaded at different addresses at system boot.
We also determine an 'anchor' symbol at the beginning of each
section to make it possible to calculate the true base address of
a section at runtime (i.e. symbol address - symbol offset).
We collect start addresses of sections that are included in the top
level section. This is used when vmlinux is linked using vmlinux.o,
because in that case, we need to look at the vmlinux.o linker map to
know what object a symbol is found in.
And finally, we process each symbol that is listed in vmlinux.map
(or vmlinux.o.map) based on the following structure:
vmlinux linked from vmlinux.a:
vmlinux.map:
<top level section>
<included section> -- might be same as top level section)
<object> -- built-in association known
<symbol> -- belongs to module(s) object belongs to
...
vmlinux linked from vmlinux.o:
vmlinux.map:
<top level section>
<included section> -- might be same as top level section)
vmlinux.o -- need to use vmlinux.o.map
<symbol> -- ignored
...
vmlinux.o.map:
<section>
<object> -- built-in association known
<symbol> -- belongs to module(s) object belongs to
...
3. As sections, objects, and symbols are processed, offset ranges are
constructed in a straight-forward way:
- If the symbol belongs to one or more built-in modules:
- If we were working on the same module(s), extend the range
to include this object
- If we were working on another module(s), close that range,
and start the new one
- If the symbol does not belong to any built-in modules:
- If we were working on a module(s) range, close that range

- Implement the SCHED_DEADLINE server infrastructure - Daniel Bristot de Oliveira's
last major contribution to the kernel:
"SCHED_DEADLINE servers can help fixing starvation issues of low priority
tasks (e.g., SCHED_OTHER) when higher priority tasks monopolize CPU
cycles. Today we have RT Throttling; DEADLINE servers should be able to
replace and improve that."
(Daniel Bristot de Oliveira, Peter Zijlstra, Joel Fernandes,
Youssef Esmat, Huang Shijie)
- Preparatory changes for sched_ext integration:
- Use set_next_task(.first) where required
- Fix up set_next_task() implementations
- Clean up DL server vs. core sched
- Split up put_prev_task_balance()
- Rework pick_next_task()
- Combine the last put_prev_task() and the first set_next_task()
- Rework dl_server
- Add put_prev_task(.next)
(Peter Zijlstra, with a fix by Tejun Heo)
- Complete the EEVDF transition and refine EEVDF scheduling:
- Implement delayed dequeue
- Allow shorter slices to wakeup-preempt
- Use sched_attr::sched_runtime to set request/slice suggestion
- Document the new feature flags
- Remove unused and duplicate-functionality fields
- Simplify & unify pick_next_task_fair()
- Misc debuggability enhancements

SCSI misc on 20240919
Updates to the usual drivers (ufs, smartpqi, NCR5380, mac_scsi, lpfc, mpi3mr). There are no user visible core changes and a whole series of minor updates and fixes.

Pull drm updates from Dave Airlie:
"This adds a couple of patches outside the drm core, all should be
acked appropriately, the string and pstore ones are the main ones that
come to mind.
Otherwise it's the usual drivers, xe is getting enabled by default on
some new hardware, we've changed the device number handling to allow
more devices, and we added some optional rust code to create QR codes
in the panic handler, an idea first suggested I think 10 years ago :-)

Pull random number generator updates from Jason Donenfeld:
"Originally I'd planned on sending each of the vDSO getrandom()
architecture ports to their respective arch trees. But as we started
to work on this, we found lots of interesting issues in the shared
code and infrastructure, the fixes for which the various archs needed
to base their work.
So in the end, this turned into a nice collaborative effort fixing up
issues and porting to 5 new architectures -- arm64, powerpc64,
powerpc32, s390x, and loongarch64 -- with everybody pitching in and
commenting on each other's code. It was a fun development cycle.
This contains:
- Numerous fixups to the vDSO selftest infrastructure, getting it
running successfully on more platforms, and fixing bugs in it.
- Additions to the vDSO getrandom & chacha selftests. Basically every
time manual review unearthed a bug in a revision of an arch patch,
or an ambiguity, the tests were augmented.
By the time the last arch was submitted for review, s390x, v1 of
the series was essentially fine right out of the gate.
- Fixes to the the generic C implementation of vDSO getrandom, to
build and run successfully on all archs, decoupling it from
assumptions we had (unintentionally) made on x86_64 that didn't
carry through to the other architectures.
- Port of vDSO getrandom to LoongArch64, from Xi Ruoyao and acked by
Huacai Chen.
- Port of vDSO getrandom to ARM64, from Adhemerval Zanella and acked
by Will Deacon.
- Port of vDSO getrandom to PowerPC, in both 32-bit and 64-bit
varieties, from Christophe Leroy and acked by Michael Ellerman.
- Port of vDSO getrandom to S390X from Heiko Carstens, the arch
maintainer.
While it'd be natural for there to be things to fix up over the course
of the development cycle, these patches got a decent amount of review
from a fairly diverse crew of folks on the mailing lists, and, for the
most part, they've been cooking in linux-next, which has been helpful
for ironing out build issues.
In terms of architectures, I think that mostly takes care of the
important 64-bit archs with hardware still being produced and running
production loads in settings where vDSO getrandom is likely to help.
Arguably there's still RISC-V left, and we'll see for 6.13 whether
they find it useful and submit a port"
