When the free segment is used up during CP disable, many write or
ioctl operations will get ENOSPC error codes, even if there are
still many blocks available. We can reproduce it in the following
steps:
dd if=/dev/zero of=f2fs.img bs=1M count=65
mkfs.f2fs -f f2fs.img
mount f2fs.img f2fs_dir -o checkpoint=disable:10%
cd f2fs_dir
i=1 ; while [[ $i -lt 50 ]] ; do (file_name=./2M_file$i ; dd \
if=/dev/random of=$file_name bs=1M count=2); i=$((i+1)); done
sync
i=1 ; while [[ $i -lt 50 ]] ; do (file_name=./2M_file$i ; truncate \
-s 1K $file_name); i=$((i+1)); done
sync
dd if=/dev/zero of=./file bs=1M count=20
In f2fs_need_SSR() function, it is allowed to use SSR to allocate
blocks when CP is disabled, so in f2fs_is_checkpoint_ready function,
can we judge the number of invalid blocks when free segment is not
enough, and return ENOSPC only if the number of invalid blocks is
also not enough.

The root cause is if checkpoint_disabling and lfs_mode are both on,
it will trigger OPU for all overwritten data, it may cost more free
segment than expected, so f2fs must account those data correctly to
calculate cosumed free segments later, and return ENOSPC earlier to
avoid run out of free segment during block allocation.

period results in not enough free segments, so when writing back root
inode will failed in f2fs_enable_checkpoint. When umount the file
system after enabling checkpoint, the root inode is dirty in
f2fs_evict_inode function, which triggers BUG_ON. The steps to
reproduce are as follows:
dd if=/dev/zero of=f2fs.img bs=1M count=55
mount f2fs.img f2fs_dir -o checkpoint=disable:10%
dd if=/dev/zero of=big bs=1M count=50

rm big
mount -o remount,checkpoint=enable f2fs_dir
umount f2fs_dir

"Here are some small USB fixes for some reported problems for 6.12-rc3.
Include in here is:
- fix for yurex driver that was caused in -rc1
- build error fix for usbg network filesystem code
- onboard_usb_dev build fix
- dwc3 driver fixes for reported errors
- gadget driver fix
- new USB storage driver quirk
- xhci resume bugfix
All of these have been in linux-next for a while with no reported
issues"

net/9p/usbg: Fix build error
USB: yurex: kill needless initialization in yurex_read
Revert "usb: yurex: Replace snprintf() with the safer scnprintf() variant"
usb: xhci: Fix problem with xhci resume from suspend
usb: misc: onboard_usb_dev: introduce new config symbol for usb5744 SMBus support
usb: dwc3: core: Stop processing of pending events if controller is halted
usb: dwc3: re-enable runtime PM after failed resume
usb: storage: ignore bogus device raised by JieLi BR21 USB sound chip
usb: gadget: core: force synchronous registration
Here is a single driver core fix, and a .mailmap update, for 6.12-rc3.
The fix is for the rust driver core bindings, turned out that the
from_raw binding wasn't a good idea (don't want to pass a pointer to a
reference counted object without actually incrementing the pointer.) So
this change fixes it up as the from_raw binding came in in -rc1.
The other change is a .mailmap update.
Both have been in linux-next for a while with no reported issues.

Fix rcuog kthread wakeup invocation from softirq context on a CPU
which has been marked offline. This can happen when new callbacks
are enqueued from a softirq on an offline CPU before it calls
rcutree_report_cpu_dead(). When this happens on NOCB configuration,
the rcuog wake-up is deferred through an IPI to an online CPU.
This is done to avoid call into the scheduler which can risk
arming the RT-bandwidth after hrtimers have been migrated out
and disabled. However, doing IPI call from softirq is not allowed
Fix this by forcing deferred rcuog wakeup through the NOCB timer
when the CPU is offline.

# echo 1 > function_profile_enabled
In that order. Create a test to test this two to make sure this does not
come back as a regression.

Pull io_uring fixes from Jens Axboe:
- Explicitly have a mshot_finished condition for IORING_OP_RECV in
multishot mode, similarly to what IORING_OP_RECVMSG has. This doesn't
fix a bug right now, but it makes it harder to actually have a bug
here if a request takes multiple iterations to finish.
- Fix handling of retry of read/write of !FMODE_NOWAIT files. If they
are pollable, that's all we need.

io_uring/rw: allow pollable non-blocking attempts for !FMODE_NOWAIT
io_uring/rw: fix cflags posting for single issue multishot read
- Fix the TPMI_RAPL_REG_DOMAIN_INFO register offset in the TPMI part of
the Intel RAPL power capping driver, make it ignore minor hardware
version mismatches (which only indicate exposing additional features)
and update register definitions in it to enable PL4 support (Zhang
Rui).
- Add Arrow Lake-U to the list of processors supporting PL4 in the MSR
part of the Intel RAPL power capping driver (Sumeet Pawnikar).
- Remove excess pci_disable_device() calls from the processor part of
the int340x thermal driver to address a warning triggered during
module unload and remove unused CPU hotplug code related to RAPL
support from it (Zhang Rui).

Unlike EMR tools which encode type information in their tool ID, tools
for AES sensors are all "generic pens". It is inappropriate to make use
of the wacom_intuos_get_tool_type function when dealing with these kinds
of devices. Instead, we should only ever report BTN_TOOL_PEN or
BTN_TOOL_RUBBER, as depending on the state of the Eraser and Invert
bits.
