scsi: bsg: Pass dev to blk_mq_alloc_queue()
When calling bsg_setup_queue() -> blk_mq_alloc_queue(), we don't pass the dev as the queuedata, but rather manually set it afterwards. Just pass dev to blk_mq_alloc_queue() to have automatically set.

mm: percpu: Include smp.h in alloc_tag.h
percpu.h depends on smp.h, but doesn't include it directly because of
circular header dependency issues; percpu.h is needed in a bunch of low
level headers.
This fixes a randconfig build error on mips:
include/linux/alloc_tag.h: In function '__alloc_tag_ref_set':
include/asm-generic/percpu.h:31:40: error: implicit declaration of function 'raw_smp_processor_id' [-Werror=implicit-function-declaration]
Reported-by: kernel test robot <lkp@intel.com>

Revert a patch causing a regression as described in the cset:
"This made a simple 'perf record -e cycles:pp make -j199' stop working on
the Ampere ARM64 system Linus uses to test ARM64 kernels, as discussed
at length in the threads in the Link tags below.
The fix provided by Ian wasn't acceptable and work to fix this will take
time we don't have at this point, so lets revert this and work on it on
the next devel cycle."

cifs: Fix missing set of remote_i_size
Occasionally, the generic/001 xfstest will fail indicating corruption in
one of the copy chains when run on cifs against a server that supports
FSCTL_DUPLICATE_EXTENTS_TO_FILE (eg. Samba with a share on btrfs). The
problem is that the remote_i_size value isn't updated by cifs_setsize()
when called by smb2_duplicate_extents(), but i_size *is*.
This may cause cifs_remap_file_range() to then skip the bit after calling
->duplicate_extents() that sets sizes.
Fix this by calling netfs_resize_file() in smb2_duplicate_extents() before
calling cifs_setsize() to set i_size.
This means we don't then need to call netfs_resize_file() upon return from
->duplicate_extents(), but we also fix the test to compare against the pre-dup
inode size.
[Note that this goes back before the addition of remote_i_size with the
netfs_inode struct. It should probably have been setting cifsi->server_eof
previously.]

take_page_off_buddy -- Failed as page is not in the buddy list.
-- Page can be putback into buddy after compaction.
page_ref_inc -- Leads to buddy page with refcnt = 1.
Then unpoison_memory() can unpoison the page and send the buddy page back
into buddy list again leading to the above bad page state warning. And
bad_page() will call page_mapcount_reset() to remove PageBuddy from buddy
page leading to later VM_BUG_ON_PAGE(!PageBuddy(page)) when trying to
allocate this page.
Fix this issue by only treating __page_handle_poison() as successful when
it returns 1.

mm: /proc/pid/smaps_rollup: avoid skipping vma after getting mmap_lock again
After switching smaps_rollup to use VMA iterator, searching for next entry
is part of the condition expression of the do-while loop. So the current
VMA needs to be addressed before the continue statement.
Otherwise, with some VMAs skipped, userspace observed memory
consumption from /proc/pid/smaps_rollup will be smaller than the sum of
the corresponding fields from /proc/pid/smaps.

nilfs2: fix potential hang in nilfs_detach_log_writer()
Syzbot has reported a potential hang in nilfs_detach_log_writer() called
during nilfs2 unmount.
Analysis revealed that this is because nilfs_segctor_sync(), which
synchronizes with the log writer thread, can be called after
nilfs_segctor_destroy() terminates that thread, as shown in the call trace
below:
nilfs_detach_log_writer
nilfs_segctor_destroy
nilfs_segctor_kill_thread --> Shut down log writer thread
flush_work
nilfs_iput_work_func
nilfs_dispose_list
iput
nilfs_evict_inode
nilfs_transaction_commit
nilfs_construct_segment (if inode needs sync)
nilfs_segctor_sync --> Attempt to synchronize with
log writer thread
*** DEADLOCK ***
Fix this issue by changing nilfs_segctor_sync() so that the log writer
thread returns normally without synchronizing after it terminates, and by
forcing tasks that are already waiting to complete once after the thread
terminates.
The skipped inode metadata flushout will then be processed together in the
subsequent cleanup work in nilfs_segctor_destroy().

nilfs2: fix unexpected freezing of nilfs_segctor_sync()
A potential and reproducible race issue has been identified where
nilfs_segctor_sync() would block even after the log writer thread writes a
checkpoint, unless there is an interrupt or other trigger to resume log
writing.
This turned out to be because, depending on the execution timing of the
log writer thread running in parallel, the log writer thread may skip
responding to nilfs_segctor_sync(), which causes a call to schedule()
waiting for completion within nilfs_segctor_sync() to lose the opportunity
to wake up.
The reason why waking up the task waiting in nilfs_segctor_sync() may be
skipped is that updating the request generation issued using a shared
sequence counter and adding an wait queue entry to the request wait queue
to the log writer, are not done atomically. There is a possibility that
log writing and request completion notification by nilfs_segctor_wakeup()
may occur between the two operations, and in that case, the wait queue
entry is not yet visible to nilfs_segctor_wakeup() and the wake-up of
nilfs_segctor_sync() will be carried over until the next request occurs.
Fix this issue by performing these two operations simultaneously within
the lock section of sc_state_lock. Also, following the memory barrier
guidelines for event waiting loops, move the call to set_current_state()
in the same location into the event waiting loop to ensure that a memory
barrier is inserted just before the event condition determination.

nilfs2: fix use-after-free of timer for log writer thread
Patch series "nilfs2: fix log writer related issues".
This bug fix series covers three nilfs2 log writer-related issues,
including a timer use-after-free issue and potential deadlock issue on
unmount, and a potential freeze issue in event synchronization found
during their analysis. Details are described in each commit log.
This patch (of 3):
A use-after-free issue has been reported regarding the timer sc_timer on
the nilfs_sc_info structure.
The problem is that even though it is used to wake up a sleeping log
writer thread, sc_timer is not shut down until the nilfs_sc_info structure
is about to be freed, and is used regardless of the thread's lifetime.
Fix this issue by limiting the use of sc_timer only while the log writer
thread is alive.

selftests/mm: compaction_test: fix bogus test success and reduce probability of OOM-killer invocation
Reset nr_hugepages to zero before the start of the test.
If a non-zero number of hugepages is already set before the start of the
test, the following problems arise:
- The probability of the test getting OOM-killed increases. Proof:
The test wants to run on 80% of available memory to prevent OOM-killing
(see original code comments). Let the value of mem_free at the start
of the test, when nr_hugepages = 0, be x. In the other case, when
nr_hugepages > 0, let the memory consumed by hugepages be y. In the
former case, the test operates on 0.8 * x of memory. In the latter,
the test operates on 0.8 * (x - y) of memory, with y already filled,
hence, memory consumed is y + 0.8 * (x - y) = 0.8 * x + 0.2 * y > 0.8 *
x. Q.E.D
- The probability of a bogus test success increases. Proof: Let the
memory consumed by hugepages be greater than 25% of x, with x and y
defined as above. The definition of compaction_index is c_index = (x -
y)/z where z is the memory consumed by hugepages after trying to
increase them again. In check_compaction(), we set the number of
hugepages to zero, and then increase them back; the probability that
they will be set back to consume at least y amount of memory again is
very high (since there is not much delay between the two attempts of
changing nr_hugepages). Hence, z >= y > (x/4) (by the 25% assumption).
Therefore, c_index = (x - y)/z <= (x - y)/y = x/y - 1 < 4 - 1 = 3
hence, c_index can always be forced to be less than 3, thereby the test
succeeding always. Q.E.D

selftests/mm: compaction_test: fix bogus test success on Aarch64
Patch series "Fixes for compaction_test", v2.
The compaction_test memory selftest introduces fragmentation in memory
and then tries to allocate as many hugepages as possible. This series
addresses some problems.
On Aarch64, if nr_hugepages == 0, then the test trivially succeeds since
compaction_index becomes 0, which is less than 3, due to no division by
zero exception being raised. We fix that by checking for division by
zero.
Secondly, correctly set the number of hugepages to zero before trying
to set a large number of them.
Now, consider a situation in which, at the start of the test, a non-zero
number of hugepages have been already set (while running the entire
selftests/mm suite, or manually by the admin). The test operates on 80%
of memory to avoid OOM-killer invocation, and because some memory is
already blocked by hugepages, it would increase the chance of OOM-killing.
Also, since mem_free used in check_compaction() is the value before we
set nr_hugepages to zero, the chance that the compaction_index will
be small is very high if the preset nr_hugepages was high, leading to a
bogus test success.
This patch (of 3):
Currently, if at runtime we are not able to allocate a huge page, the test
will trivially pass on Aarch64 due to no exception being raised on
division by zero while computing compaction_index. Fix that by checking
for nr_hugepages == 0. Anyways, in general, avoid a division by zero by
exiting the program beforehand. While at it, fix a typo, and handle the
case where the number of hugepages may overflow an integer.

The root cause is that HWPoison flag will be set for huge_zero_folio
without increasing the folio refcnt. But then unpoison_memory() will
decrease the folio refcnt unexpectedly as it appears like a successfully
hwpoisoned folio leading to VM_BUG_ON_PAGE(page_ref_count(page) == 0) when
releasing huge_zero_folio.
Skip unpoisoning huge_zero_folio in unpoison_memory() to fix this issue.
We're not prepared to unpoison huge_zero_folio yet.

tracefs/eventfs fixes and updates for v6.10:
Bug fixes:
- The eventfs directories need to have unique inode numbers. Make sure that
they do not get the default file inode number.
- Update the inode uid and gid fields on remount.
When a remount happens where a uid and/or gid is specified, all the tracefs
files and directories should get the specified uid and/or gid. But this
can be sporadic when some uids were assigned already. There's already
a list of inodes that are allocated. Just update their uid and gid fields
at the time of remount.
- Update the eventfs_inodes on remount from the top level "events" descriptor.
There was a bug where not all the eventfs files or directories where
getting updated on remount. One fix was to clear the SAVED_UID/GID
flags from the inode list during the iteration of the inodes during
the remount. But because the eventfs inodes can be freed when the last
referenced is released, not all the eventfs_inodes were being updated.
This lead to the ownership selftest to fail if it was run a second
time (the first time would leave eventfs_inodes with no corresponding
tracefs_inode).
Instead, for eventfs_inodes, only process the "events" eventfs_inode
from the list iteration, as it is guaranteed to have a tracefs_inode
(it's never freed while the "events" directory exists). As it has
a list of its children, and the children have a list of their children,
just iterate all the eventfs_inodes from the "events" descriptor and
it is guaranteed to get all of them.
- Clear the EVENT_INODE flag from the tracefs_drop_inode() callback.
Currently the EVENTFS_INODE FLAG is cleared in the tracefs_d_iput()
callback. But this is the wrong location. The iput() callback is
called when the last reference to the dentry inode is hit. There could
be a case where two dentry's have the same inode, and the flag will
be cleared prematurely. The flag needs to be cleared when the last
reference of the inode is dropped and that happens in the inode's
drop_inode() callback handler.
Clean ups:
- Consolidate the creation of a tracefs_inode for an eventfs_inode
A tracefs_inode is created for both files and directories of the
eventfs system. It is open coded. Instead, consolidate it into a
single eventfs_get_inode() function call.
- Remove the eventfs getattr and permission callbacks.
The permissions for the eventfs files and directories are updated
when the inodes are created, on remount, and when the user sets
them (via setattr). The inodes hold the current permissions so
there is no need to have custom getattr or permissions callbacks
as they will more likely cause them to be incorrect. The inode's
permissions are updated when they should be updated. Remove the
getattr and permissions inode callbacks.
- Do not update eventfs_inode attributes on creation of inodes.
The eventfs_inodes attribute field is used to store the permissions
of the directories and files for when their corresponding inodes
are freed and are created again. But when the creation of the inodes
happen, the eventfs_inode attributes are recalculated. The
recalculation should only happen when the permissions change for
a given file or directory. Currently, the attribute changes are
just being set to their current files so this is not a bug, but
it's unnecessary and error prone. Stop doing that.
- The events directory inode is created once when the events directory
is created and deleted when it is deleted. It is now updated on
remount and when the user changes the permissions. There's no need
to use the eventfs_inode of the events directory to store the
events directory permissions. But using it to store the default
permissions for the files within the directory that have not been
updated by the user can simplify the code.

genirq/irqdesc: Prevent use-after-free in irq_find_at_or_after()
irq_find_at_or_after() dereferences the interrupt descriptor which is
returned by mt_find() while neither holding sparse_irq_lock nor RCU read
lock, which means the descriptor can be freed between mt_find() and the
dereference:
CPU0 CPU1
desc = mt_find()
delayed_free_desc(desc)
irq_desc_get_irq(desc)
The use-after-free is reported by KASAN:
