Pull btrfs fixes from David Sterba:
"First batch of fixes. Among them there are two updates to sysfs and
ioctl which are not strictly fixes but are used for testing so there's
no reason to delay them.
- fix block group item corruption after inserting new block group
- fix extent map logging bit not cleared for split maps after
dropping range
- fix calculation of unusable block group space reporting bogus
values due to 32/64b division
- fix unnecessary increment of read error stat on write error
- improve error handling in inode update
- export per-device fsid in DEV_INFO ioctl to distinguish seeding
devices, needed for testing

Pull io_uring fixes from Jens Axboe:
- Stop setting PF_NO_SETAFFINITY on io-wq workers.
This has been reported in the past as it confuses some applications,
as some of their threads will fail with -1/EINVAL if attempted
affinitized. Most recent report was on cpusets, where enabling that
with io-wq workers active will fail.
Just deal with the mask changing by checking when a worker times out,
and then exit if we have no work pending.
- Fix an issue with passthrough support where we don't properly check
if the file type has pollable uring_cmd support.
- Fix a reported W=1 warning on a variable being set and unused. Add a
special helper for iterating these lists that doesn't save the
previous list element, if that iterator never ends up using it.

Pull perf tools fixes from Arnaldo Carvalho de Melo:
- Add Adrian Hunter to MAINTAINERS as a perf tools reviewer
- Sync various tools/ copies of kernel headers with the kernel sources,
this time trying to avoid first merging with upstream to then update
but instead copy from upstream so that a merge is avoided and the end
result after merging this pull request is the one expected,
tools/perf/check-headers.sh (mostly) happy, less warnings while
building tools/perf/
- Fix counting when initial delay configured by setting
perf_attr.enable_on_exec when starting workloads from the perf
command line
- Don't avoid emitting a PERF_RECORD_MMAP2 in 'perf inject
--buildid-all' when that record comes with a build-id, otherwise we
end up not being able to resolve symbols
- Don't use comma as the CSV output separator the "stat+csv_output"
test, as comma can appear on some tests as a modifier for an event,
use @ instead, ditto for the JSON linter test
- The offcpu test was looking for some bits being set on
task_struct->prev_state without masking other bits not important for
this specific 'perf test', fix it

The recent fix for the deferred I/O by the commit
3efc61d95259 ("fbdev: Fix invalid page access after closing deferred I/O devices")
caused a regression when the same fb device is opened/closed while
it's being used. It resulted in a frozen screen even if something
is redrawn there after the close. The breakage is because the patch
was made under a wrong assumption of a single open; in the current
code, fb_deferred_io_release() cleans up the page mapping of the
pageref list and it calls cancel_delayed_work_sync() unconditionally,
where both are no correct behavior for multiple opens.
This patch adds a refcount for the opens of the device, and applies
the cleanup only when all files get closed.
As both fb_deferred_io_open() and _close() are called always in the
fb_info lock (mutex), it's safe to use the normal int for the
refcounting.
Also, a useless BUG_ON() is dropped.

The function hist_field_name() cannot handle being passed a NULL field
parameter. It should never be NULL, but due to a previous bug, NULL was
passed to the function and the kernel crashed due to a NULL dereference.
Mark Rutland reported this to me on IRC.
The bug was fixed, but to prevent future bugs from crashing the kernel,
check the field and add a WARN_ON() if it is NULL.

Histogram values can not be strings, stacktraces, graphs, symbols,
syscalls, or grouped in buckets or log. Give an error if a value is set to
do so.
Note, the histogram code was not prepared to handle these modifiers for

Actually, the drm_dev_enter in psp_cmd_submit_buf does not
protect anything. If DRM device is unplugged, it will always
check the condition in WARN_ON. So drop drm_dev_enter and
drm_dev_exit in psp_cmd_submit_buf.

drm_dev_unplug

The same strapping initialization issue that happened on NBIO 7.5.1
appears to be happening on NBIO 7.3.0.
Apply the same fix to 7.3.0 as well.
Note: This workaround relies upon the integrated GPU being enabled
in BIOS. If the integrated GPU is disabled in BIOS a different
workaround will be required.

Multi Circular Queue doesn't use outstanding_reqs. However, the UFS clock
scaling functions use outstanding_reqs to determine if there are requests
pending. When MCQ is enabled, this check always returns false.
Hence use active_reqs to check if there are pending requests.

Some storage, such as AIX VDASD (virtual storage) and IBM 2076 (front
end), fail as a result of commit c92a6b5d6335 ("scsi: core: Query VPD
size before getting full page").
That commit changed getting SCSI VPD pages so that we now read just
enough of the page to get the actual page size, then read the whole
page in a second read. The problem is that the above mentioned
hardware returns zero for the page size, because of a firmware
error. In such cases, until the firmware is fixed, this new blacklist
flag says to revert to the original method of reading the VPD pages,
i.e. try to read a whole buffer's worth on the first try.
[mkp: reworked somewhat]

We're currently using stop_machine() to update ftrace & kprobes, which
means that the thread that takes text_mutex during may not be the same
as the thread that eventually patches the code. This isn't actually a
race because the lock is still held (preventing any other concurrent
accesses) and there is only one thread running during stop_machine(),
but it does trigger a lockdep failure.
This patch just elides the lockdep check during stop_machine.

A user should be allowed to take out a lease via an idmapped mount if
the fsuid matches the mapped uid of the inode. generic_setlease() is
checking the unmapped inode uid, causing these operations to be denied.
Fix this by comparing against the mapped inode uid instead of the
unmapped uid.

The i2cdev_{at,de}tach_adapter() callbacks are used for two purposes:
1. As notifier callbacks, when (un)registering I2C adapters created or
destroyed after i2c_dev_init(),
2. As bus iterator callbacks, for registering already existing
adapters from i2c_dev_init(), and for cleanup.
Unfortunately both use cases expect different return values: the former
expects NOTIFY_* return codes, while the latter expects zero or error
codes, and aborts in case of error.
Hence in case 2, as soon as i2cdev_{at,de}tach_adapter() returns
(non-zero) NOTIFY_OK, the bus iterator aborts. This causes (a) only the
first already existing adapter to be registered, leading to missing
/dev/i2c-* entries, and (b) a failure to unregister all but the first
I2C adapter during cleanup.
Fix this by introducing separate callbacks for the bus iterator,
wrapping the notifier functions, and always returning succes.
Any errors inside these callback functions are unlikely to happen, and
are fatal anyway.

Commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back
type") introduced a new probe callback to convert i2c init routines to
not take an i2c_device_id parameter. Now that all in-tree drivers are
converted to the temporary .probe_new() callback, .probe() can be
modified to match the desired prototype.
Now that .probe() and .probe_new() have the same semantic, they can be
defined as members of an anonymous union to save some memory and
simplify the core code a bit.

msm-fixes for v6.3-rc2
- Fix for possible invalid ptr free in submit ioctl syncobj cleanup path.
- Synchronize GMU removal in driver teardown path
- a5xx preemption fixes
- Fix runpm imbalance at unbind
- DPU hw catalog fixes:
- set DPU_MDP_PERIPH_0_REMOVED for sc8280xp as this is another chipset
where the PERIPH_0 block of registers is not there
- fix the DPU features supported in QCM2290 by comparing it with the
downstream device tree
- fix the length of registers in the sc7180_ctl from 0xe4 to 0x1dc
- fix the max mixer line width for sm6115 and qcm2290 chipsets in the
DPU catalog
- fix the scaler version on sm8550, sc8280xp, sm8450, sm8250, sm8350
and sm6115. This was incorrectly populated on the SW version of the
scaler library and not the scaler HW version
- Drop dim layer support for msm8998 as its not indicated to be
supported in the downstream DTSI
- fix the DPU_CLK_CTRL bits for msm 8998 sspp blocks
- Use DPU_CLK_CTRL_DMA* prefix instead of DPU_CLK_CTRL_CURSOR*
for all chipsets for the DMA sspp blocks
- fix the ping-pong block base address for sc7280 in the DPU HW catalog
- Fix stack corruption issue in the dpu_hw_ctl_setup_blendstage() function
as it was causing a negative left shift by protecting against an invalid
index
- Clear the DSPP reservations in dpu_rm_release(). This was missed out and
as as result the DSPP was not released from the resource manager global
state.

If io_uring.o is built with W=1, it triggers a warning:
io_uring/io_uring.c: In function ‘__io_submit_flush_completions’:
io_uring/io_uring.c:1502:40: warning: variable ‘prev’ set but not used [-Wunused-but-set-variable]
1502 | struct io_wq_work_node *node, *prev;
| ^~~~
which is due to the wq_list_for_each() iterator always keeping a 'prev'
variable. Most users need this to remove an entry from a list, for
example, but __io_submit_flush_completions() never does that.
Add a basic helper that doesn't track prev instead, and use that in
that function.
