Some systems have an ACPI video bus but not ACPI video devices with
backlight capability. On these devices brightness key-presses are
(logically) not reported through the ACPI video bus.
Change how acpi_video_handles_brightness_key_presses() determines if
brightness key-presses are handled by the ACPI video driver to avoid
vendor specific drivers/platform/x86 drivers filtering out their
brightness key-presses even though they are the only ones reporting
these presses.

On some Panasonic models the volume up/down/mute keypresses get
reported both through the Panasonic ACPI HKEY interface as well as
through the atkbd device.
Filter out the atkbd scan-codes for these to avoid reporting presses
twice.
Note normally we would leave the filtering of these to userspace by mapping
the scan-codes to KEY_UNKNOWN through /lib/udev/hwdb.d/60-keyboard.hwdb.
However in this case that would cause regressions since we were filtering
the Panasonic ACPI HKEY events before, so filter these in the kernel.

Commit ac0126a01735 ("soc: qcom: cmd-db: replace strncpy() with
strscpy_pad()") breaks booting on my sc7280-herobrine-herobrine
device. From printouts I see that at bootup the function is called
with an id of "lnbclka2" which is 8 bytes big.
Previously all 8 bytes of this string were copied to the
destination. Now only 7 bytes will be copied since strscpy_pad() saves
a byte for '\0' termination.
We don't need the '\0' termination in the destination. Let's go back
to strncpy(). According to the warning:
If a caller is using non-NUL-terminated strings, strncpy() can still
be used, but destinations should be marked with the __nonstring
attribute to avoid future compiler warnings.
...so we'll do that.
While we're at it, let's change the query array to use
"sizeof(ent->id)" so it can't possibly go out of sync with our later
copy.

There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].
This code was transformed with the help of Coccinelle:
(linux-5.19-rc2$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch)
@@
identifier S, member, array;
type T1, T2;
@@
struct S {
...
T1 member;
T2 array[
- 0
];
};
-fstrict-flex-arrays=3 is coming and we need to land these changes
to prevent issues like these in the short future:
../fs/minix/dir.c:337:3: warning: 'strcpy' will always overflow; destination buffer has size 0,
but the source string has length 2 (including NUL byte) [-Wfortify-source]
strcpy(de3->name, ".");
^
Since these are all [0] to [] changes, the risk to UAPI is nearly zero. If
this breaks anything, we can use a union with a new member name.

When a filesystem is mounted with a name that starts with a #:
# mount '#name' /mnt/bad -t tmpfs
this will cause the entry to look like this (leading space added so
that git does not strip it out):
#name /mnt/bad tmpfs rw,seclabel,relatime,inode64 0 0
This breaks getmntent and any code that aims to parse fstab as well as
/proc/mounts with the same logic since they need to strip leading spaces
or skip over comment lines, due to which they report incorrect output or
skip over the line respectively.
Solve this by translating the hash character into its octal encoding
equivalent so that applications can decode the name correctly.

The BPF subsystem consists of a large number of pieces. There is not a
single person that understands it all. Yet reviews are crucially important
for the BPF community to provide productive quality feedback to contributors
in a timely manner and therefore to ultimately expand the number of active
developers in the community.
So far, the BPF community had a two-stage review system, that is, a weekly
rotation among 7 developers (Alexei, Daniel, Andrii, Martin, Song, Yonghong,
John) as a first-level review of all inbound patches accompanied by a BPF CI
system which runs the in-tree BPF selftests to check for regressions for
every new patch, and then, a final check by Alexei, Daniel, Andrii to apply
the patches to either bpf or bpf-next trees.
This system worked well for the last ~3.5 years, but clearly reaches its
limits these days as it does not scale enough. Especially, as we also need
to allow enough room for every developer to contribute patches themselves,
integrate with their day to day job, and in particular avoid burnout. We
want to better scale both horizontally and vertically going forward.
On the horizontal scale, we are adding more developers (KP, Stan, Hao, Jiri)
to the overall core reviewer team, thus growing to 11 people in total. The
weekly rotation for the horizontal oncall reviewer is shortened to 1/2 week
(Mo - Wed and Thur - Fri). Instead of just patches, the coverage however
extends also generally to triage and reply to mailing list traffic (e.g. RFCs,
questions, etc).
On the vertical scale, there is clearly a need for deep expertise areas to
assign dedicated maintainer/reviewer teams that are responsible for code
reviews and help with design of individual building blocks. To some degree
we have been doing this implicitly, but the point is to formalize the teams
and commitment.
There is an overlap between areas and boundaries are intentionally grey. These
additional entries provide a guidance on who has to look at the patches. The
patch series which span multiple areas will be looked at by multiple people.
The vertical review with areas of deep expertise are bundled at the same time
with the horizontal side.
This patch cleans up a bit the BPF entries, adds mentioned developers to
the horizontal scale and creates new sub-entries with teams for developers
committing to the above outlined vertical scale. Also, pw.git tools we use
for BPF tree maintenance have been updated with a new pw-schedule script to
semi-automate vertical oncall review rotation.

Align refcount behaviour for amdgpu_job embedded HW fence with
classic pointer style HW fences by increasing refcount each
time emit is called so amdgpu code doesn't need to make workarounds
using amdgpu_job.job_run_counter to keep the HW fence refcount balanced.
Also since in the previous patch we resumed setting s_fence->parent to NULL
in drm_sched_stop switch to directly checking if job->hw_fence is
signaled to short circuit reset if already signed.

Problem:
This patch caused negative refcount as described in [1] because
for that case parent fence did not signal by the time of drm_sched_stop and hence
kept in pending list the assumption was they will not signal and
so fence was put to account for the s_fence->parent refcount but for
amdgpu which has embedded HW fence (always same parent fence)
drm_sched_fence_release_scheduled was always called and would
still drop the count for parent fence once more. For jobs that
never signaled this imbalance was masked by refcount bug in
amdgpu_fence_driver_clear_job_fences that would not drop
refcount on the fences that were removed from fence drive
fences array (against prevois insertion into the array in
get in amdgpu_fence_emit).
Fix:
Revert this patch and by setting s_job->s_fence->parent to NULL
as before prevent the extra refcount drop in amdgpu when
drm_sched_fence_release_scheduled is called on job release.
Also - align behaviour in drm_sched_resubmit_jobs_ext with that of
drm_sched_main when submitting jobs - take a refcount for the
new parent fence pointer and drop refcount for original kref_init
for new HW fence creation (or fake new HW fence in amdgpu - see next patch).

Problem:
After we start handling timed out jobs we assume there fences won't be
signaled but we cannot be sure and sometimes they fire late. We need
to prevent concurrent accesses to fence array from
amdgpu_fence_driver_clear_job_fences during GPU reset and amdgpu_fence_process
from a late EOP interrupt.
Fix:
Before accessing fence array in GPU disable EOP interrupt and flush
all pending interrupt handlers for amdgpu device's interrupt line.
