Use command_id instead of req->tag in trace_nvme_complete_rq(),

raid5_get_active_stripe() can sleep in various situations and it
is called by make_stripe_request() while inside the
prepare_to_wait()/finish_wait() section. Nested waits like this are
not supported.
This was noticed while making other changes that add different sleeps
to raid5_get_active_stripe() that caused a WARNING with
CONFIG_DEBUG_ATOMIC_SLEEP.
No ill effects have been noticed with the code as is, but theoretically
a nested and here could cause a dead lock so it should be fixed.
To fix this, convert the prepare_to_wait() call to use wake_woken()
which supports nested sleeps.

md/raid5: Fix sectors_to_do bitmap overflow in raid5_make_request()
For unaligned IO that have nearly maximum sectors, the number of stripes
will end up being one greater than the size of the bitmap. When this
happens, the last stripe in the IO will not be processed as it should
be, resulting in data corruption.
However, this is not normally seen when the backing block devices have
4K physical block sizes since the block layer will split the request
before that happens.
To fix this increase the bitmap size by one bit and ensure the full
number of stripes are checked when calling find_first_bit().

On powerpc, 'perf trace' is crashing with a SIGSEGV when trying to
process a perf.data file created with 'perf trace record -p':
#0 0x00000001225b8988 in syscall_arg__scnprintf_augmented_string <snip> at builtin-trace.c:1492
#1 syscall_arg__scnprintf_filename <snip> at builtin-trace.c:1492
#2 syscall_arg__scnprintf_filename <snip> at builtin-trace.c:1486
#3 0x00000001225bdd9c in syscall_arg_fmt__scnprintf_val <snip> at builtin-trace.c:1973
#4 syscall__scnprintf_args <snip> at builtin-trace.c:2041
#5 0x00000001225bff04 in trace__sys_enter <snip> at builtin-trace.c:2319
That points to the below code in tools/perf/builtin-trace.c:
/*
* If this is raw_syscalls.sys_enter, then it always comes with the 6 possible
* arguments, even if the syscall being handled, say "openat", uses only 4 arguments
* this breaks syscall__augmented_args() check for augmented args, as we calculate
* syscall->args_size using each syscalls:sys_enter_NAME tracefs format file,
* so when handling, say the openat syscall, we end up getting 6 args for the
* raw_syscalls:sys_enter event, when we expected just 4, we end up mistakenly
* thinking that the extra 2 u64 args are the augmented filename, so just check
* here and avoid using augmented syscalls when the evsel is the raw_syscalls one.
*/
if (evsel != trace->syscalls.events.sys_enter)
augmented_args = syscall__augmented_args(sc, sample, &augmented_args_size, trace->raw_augmented_syscalls_args_size);
As the comment points out, we should not be trying to augment the args
for raw_syscalls. However, when processing a perf.data file, we are not
initializing those properly. Fix the same.

I'm sorry to do such change at rc6 time but the revert is IMO the

random: cap jitter samples per bit to factor of HZ
Currently the jitter mechanism will require two timer ticks per
iteration, and it requires N iterations per bit. This N is determined
with a small measurement, and if it's too big, it won't waste time with
jitter entropy because it'd take too long or not have sufficient entropy
anyway.
With the current max N of 32, there are large timeouts on systems with a
small CONFIG_HZ. Rather than set that maximum to 32, instead choose a
factor of CONFIG_HZ. In this case, 1/30 seems to yield sane values for
different configurations of CONFIG_HZ.

The console_stop() and console_start() functions call pr_flush().
When suspending, these functions are called by the serial subsystem
while the serial port is suspended. In this scenario, if there are
any pending messages, a call to pr_flush() will always result in a
timeout because the serial port cannot make forward progress. This
causes longer suspend and resume times.

ubsan: disable UBSAN_DIV_ZERO for clang
Building with UBSAN_DIV_ZERO with clang produces numerous fallthrough
warnings from objtool.
In the case of uncheck division, UBSAN_DIV_ZERO may introduce new
control flow to check for division by zero.
Because the result of the division is undefined, LLVM may optimize the
control flow such that after the call to __ubsan_handle_divrem_overflow
doesn't matter. If panic_on_warn was set,
__ubsan_handle_divrem_overflow would panic.
The problem is is that panic_on_warn is run time configurable. If it's
disabled, then we cannot guarantee that we will be able to recover
safely. Disable this config for clang until we can come up with a
solution in LLVM.

"Including fixes from netfilter, bpf and wireless.
Still no major regressions, the release continues to be calm. An
uptick of fixes this time around due to trivial data race fixes and
patches flowing down from subtrees.
There has been a few driver fixes (particularly a few fixes for false
positives due to
66e4c8d95008 which went into -next in May!) that make
me worry the wide testing is not exactly fully through.
So "calm" but not "let's just cut the final ASAP" vibes over here.
Current release - regressions:
- wifi: rtw88: fix write to const table of channel parameters
Current release - new code bugs:
- mac80211: add gfp_t arg to ieeee80211_obss_color_collision_notify
- mlx5:
- TC, allow offload from uplink to other PF's VF
- Lag, decouple FDB selection and shared FDB
- Lag, correct get the port select mode str
- bnxt_en: fix and simplify XDP transmit path
- r8152: fix accessing unset transport header
Previous releases - regressions:
- conntrack: fix crash due to confirmed bit load reordering (after
atomic -> refcount conversion)
- stmmac: dwc-qos: disable split header for Tegra194
Previous releases - always broken:
- mlx5e: ring the TX doorbell on DMA errors
- bpf: make sure mac_header was set before using it
- mac80211: do not wake queues on a vif that is being stopped
- mac80211: fix queue selection for mesh/OCB interfaces
- ip: fix dflt addr selection for connected nexthop
- seg6: fix skb checksums for SRH encapsulation/insertion
- xdp: fix spurious packet loss in generic XDP TX path
- bunch of sysctl data race fixes

ACPI: video: Fix acpi_video_handles_brightness_key_presses()
Commit
3a0cf7ab8df3 ("ACPI: video: Change how we determine if brightness
key-presses are handled") made acpi_video_handles_brightness_key_presses()
report false when none of the ACPI Video Devices support backlight control.
But it turns out that at least on a Dell Inspiron N4010 there is no ACPI
backlight control, yet brightness hotkeys are still reported through
the ACPI Video Bus; and since acpi_video_handles_brightness_key_presses()
now returns false, brightness keypresses are now reported twice.
To fix this rename the has_backlight flag to may_report_brightness_keys and
also set it the first time a brightness key press event is received.
Depending on the delivery of the other ACPI (WMI) event vs the ACPI Video
Bus event this means that the first brightness key press might still get
reported twice, but all further keypresses will be filtered as before.
Note that this relies on other drivers reporting brightness key events
calling acpi_video_handles_brightness_key_presses() when delivering
the events (rather then once during driver probe). This is already
required and documented in include/acpi/video.h:
/*
* Note: The value returned by acpi_video_handles_brightness_key_presses()
* may change over time and should not be cached.
*/

um: Replace to_phys() and to_virt() with less generic function names
The UML function names to_virt() and to_phys() are exposed by UML
headers, and are very generic and may be defined by drivers. As it
turns out, commit
9409c9b6709e ("pmem: refactor pmem_clear_poison()")
did exactly that.
This results in build errors such as the following when trying to build
um:allmodconfig:
drivers/nvdimm/pmem.c: In function ‘pmem_dax_zero_page_range’:
./arch/um/include/asm/page.h:105:20: error: too few arguments to function ‘to_phys’
105 | #define __pa(virt) to_phys((void *) (unsigned long) (virt))
| ^~~~~~~
Use less generic function names for the um specific to_phys() and
to_virt() functions to fix the problem and to avoid similar problems in
the future.
