The default nvme_tcp_wq will use all CPUs to process tasks. Sometimes it is
necessary to set CPU affinity to improve performance.
A new module parameter wq_unbound is added here. If set to true, users can
configure cpu affinity through
/sys/devices/virtual/workqueue/nvme_tcp_wq/cpumask.

This commit adds NVME_QUIRK_NO_DEEPEST_PS and NVME_QUIRK_BOGUS_NID for
device [126f:2262], which appears to be a generic VID:PID pair used for
many SSDs based on the Silicon Motion SM2262/SM2262EN controller.
Two of my SSDs with this VID:PID pair exhibit the same behavior:
* They frequently have trouble exiting the deepest power state (5),
resulting in the entire disk unresponsive.
Verified by setting nvme_core.default_ps_max_latency_us=10000 and
observing them behaving normally.
* They produce all-zero nguid and eui64 with `nvme id-ns` command.
The offending products are:
* HP SSD EX950 1TB
* HIKVISION C2000Pro 2TB

As per the hardware team, TIEN and TINT source should not set at the same
time due to a possible hardware race leading to spurious IRQ.
Currently on some scenarios hardware settings for TINT detection is not in
sync with TINT source as the enable/disable overrides source setting value
leading to hardware inconsistent state. For eg: consider the case GPIOINT0
is used as TINT interrupt and configuring GPIOINT5 as edge type. During
rzg2l_irq_set_type(), TINT source for GPIOINT5 is set. On disable(),
clearing of the entire bytes of TINT source selection for GPIOINT5 is same
as GPIOINT0 with TIEN disabled. Apart from this during enable(), the
setting of GPIOINT5 with TIEN results in spurious IRQ as due to a HW race,
it is possible that IP can use the TIEN with previous source value
(GPIOINT0).
So, just update TIEN during enable/disable as TINT source is already set
during rzg2l_irq_set_type(). This will make the consistent hardware
settings for detection method tied with TINT source and allows to simplify
the code.

Pull f2fs update from Jaegeuk Kim:
"In this round, there are a number of updates on mainly two areas:
Zoned block device support and Per-file compression. For example,
we've found several issues to support Zoned block device especially
having large sections regarding to GC and file pinning used for
Android devices. In compression side, we've fixed many corner race
conditions that had broken the design assumption.
Enhancements:
- Support file pinning for Zoned block device having large section
- Enhance the data recovery after sudden power cut on Zoned block
device
- Add more error injection cases to easily detect the kernel panics
- add a proc entry show the entire disk layout
- Improve various error paths paniced by BUG_ON in block allocation
and GC
- support SEEK_DATA and SEEK_HOLE for compression files
Bug fixes:
- avoid use-after-free issue in f2fs_filemap_fault
- fix some race conditions to break the atomic write design
assumption
- fix to truncate meta inode pages forcely
- resolve various per-file compression issues wrt the space

There are reports that since version 6.7 update-grub fails to find the
device of the root on systems without initrd and on a single device.
This looks like the device name changed in the output of
/proc/self/mountinfo:
6.5-rc5 working
18 1 0:16 / / rw,noatime - btrfs /dev/sda8 ...
6.7 not working:
17 1 0:15 / / rw,noatime - btrfs /dev/root ...
and "update-grub" shows this error:
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?)
This looks like it's related to the device name, but grub-probe
recognizes the "/dev/root" path and tries to find the underlying device.
However there's a special case for some filesystems, for btrfs in
particular.
The generic root device detection heuristic is not done and it all
relies on reading the device infos by a btrfs specific ioctl. This ioctl
returns the device name as it was saved at the time of device scan (in
this case it's /dev/root).
The change in 6.7 for temp_fsid to allow several single device
filesystem to exist with the same fsid (and transparently generate a new
UUID at mount time) was to skip caching/registering such devices.
This also skipped mounted device. One step of scanning is to check if
the device name hasn't changed, and if yes then update the cached value.
This broke the grub-probe as it always read the device /dev/root and
couldn't find it in the system. A temporary workaround is to create a
symlink but this does not survive reboot.
The right fix is to allow updating the device path of a mounted
filesystem even if this is a single device one.
In the fix, check if the device's major:minor number matches with the
cached device. If they do, then we can allow the scan to happen so that
device_list_add() can take care of updating the device path. The file
descriptor remains unchanged.
This does not affect the temp_fsid feature, the UUID of the mounted
filesystem remains the same and the matching is based on device major:minor
which is unique per mounted filesystem.
This covers the path when the device (that exists for all mounted
devices) name changes, updating /dev/root to /dev/sdx. Any other single
device with filesystem and is not mounted is still skipped.
Note that if a system is booted and initial mount is done on the
/dev/root device, this will be the cached name of the device. Only after
the command "btrfs device scan" it will change as it triggers the
rename.
The fix was verified by users whose systems were affected.

[ a.k.a. Revert "Revert "ARM64: Dynamically allocate cpumasks and
increase supported CPUs to 512""; originally reverted because of a
bug in the cpufreq-dt code not using zalloc_cpumask_var() ]
Currently defconfig selects NR_CPUS=256, but some vendors (e.g. Ampere
Computing) are planning to ship systems with 512 CPUs. So that all CPUs on
these systems can be used with defconfig, we'd like to bump NR_CPUS to 512.
Therefore this patch increases the default NR_CPUS from 256 to 512.
As increasing NR_CPUS will increase the size of cpumasks, there's a fear that
this might have a significant impact on stack usage due to code which places
cpumasks on the stack. To mitigate that concern, we can select
CPUMASK_OFFSTACK. As that doesn't seem to be a problem today with
NR_CPUS=256, we only select this when NR_CPUS > 256.
CPUMASK_OFFSTACK configures the cpumasks in the kernel to be
dynamically allocated. This was used in the X86 architecture in the
past to enable support for larger CPU configurations up to 8k cpus.
With that is becomes possible to dynamically size the allocation of
the cpu bitmaps depending on the quantity of processors detected on
bootup. Memory used for cpumasks will increase if the kernel is
run on a machine with more cores.
Further increases may be needed if ARM processor vendors start
supporting more processors. Given the current inflationary trends
in core counts from multiple processor manufacturers this may occur.
There are minor regressions for hackbench. The kernel data size
for 512 cpus is smaller with offstack than with onstack.
Benchmark results using hackbench average over 10 runs of
hackbench -s 512 -l 2000 -g 15 -f 25 -P

Some architectures, like aarch64 ones, need a dtb file to configure the
hardware. The default dtb file can be preloaded from u-boot, but the final
and/or more complete dtb file needs to be able to be loaded later from
rootfs.
Add the possible dtb files to the kernel rpm and mimic Fedora shipping
process, storing the dtb files in the module directory. These dtb files
will be copied to /boot directory by the install scripts, but add fallback
just in case, checking if the content in /boot directory is correct.
Mark the files installed to /boot as %ghost to make sure they will be
removed when the package is uninstalled.
Tested with Fedora Rawhide (x86_64 and aarch64) with dnf and rpm tools.
In addition, fallback was also tested after modifying the install scripts.

Recently we tested the headphone playback on 2 LG machines, if we set
the volume to the max value or near to the max value, the sound is too
loud, it could even bring harm to listeners.
A workaround is to decrease the max volume to a reasonable value for
the headphone's amplifier, then the users couldn't set the volume
bigger than that value from the userspace.

The __string() helper macro of the TRACE_EVENT() macro is used to
determine how much of the ring buffer needs to be allocated to fit the
given source string. Some trace events have a string that is dependent on
another variable that could be NULL, and in those cases the string is
passed in to be NULL.
The __string() macro can handle being passed in a NULL pointer for which
it will turn it into "(null)". It does that with:
strlen((src) ? (const char *)(src) : "(null)") + 1
But if src itself has the same conditional type it can confuse the
compiler. That is:
__string(r ? dev(r)->name : NULL)
Would turn into:
strlen((r ? dev(r)->name : NULL) ? (r ? dev(r)->name : NULL) : "(null)" + 1
For which the compiler thinks that NULL is being passed to strlen() and
gives this kind of warning:
./include/trace/stages/stage5_get_offsets.h:50:21: warning: argument 1 null where non-null expected [-Wnonnull]
50 | strlen((src) ? (const char *)(src) : "(null)") + 1)
Instead, create a static inline function that takes the src string and
will return the string if it is not NULL and will return "(null)" if it
is. This will then make the strlen() line:
strlen(__string_src(src)) + 1
Where the compiler can see that strlen() will not end up with NULL and
does not warn about it.
Note that this depends on commit 51270d573a8d ("tracing/net_sched: Fix
tracepoints that save qdisc_dev() as a string") being applied, as passing
the qdisc_dev() into __string_src() will give an error.

The WARN_ON() check in __assign_str() to catch where the source variable
to the macro doesn't match the source variable to __string() gives an
error in clang:
>> include/trace/events/sunrpc.h:703:4: warning: result of comparison against a string literal is unspecified (use an explicit string comparison function instead) [-Wstring-compare]
670 | __assign_str(progname, "unknown");
That's because the __assign_str() macro has:
WARN_ON_ONCE((src) != __data_offsets.dst##_ptr_);
Where "src" is a string literal. Clang warns when comparing a string
literal directly as it is undefined to what the value of the literal is.
Since this is still to make sure the same string that goes to __string()
is the same as __assign_str(), for string literals do a test for that and
then use strcmp() in those cases
Note that this depends on commit 51270d573a8d ("tracing/net_sched: Fix
tracepoints that save qdisc_dev() as a string") being applied, as this was
what found that bug.

There are two WARN_ON*() warnings in tracepoint.h that deal with RCU
usage. But when they trigger, especially from using a TRACE_EVENT()
macro, the information is not very helpful and is confusing:
------------[ cut here ]------------
WARNING: CPU: 0 PID: 0 at include/trace/events/lock.h:24 lock_acquire+0x2b2/0x2d0
Where the above warning takes you to:
TRACE_EVENT(lock_acquire, <<<--- line 24 in lock.h
TP_PROTO(struct lockdep_map *lock, unsigned int subclass,
int trylock, int read, int check,
struct lockdep_map *next_lock, unsigned long ip),
[..]
Change the WARN_ON_ONCE() to WARN_ONCE() and add a string that allows
someone to search for exactly where the bug happened.

Currently ftrace only dumps the global trace buffer on an OOPs. For
debugging a production usecase, instance trace will be helpful to
check specific problems since global trace buffer may be used for
other purposes.
This patch extend the ftrace_dump_on_oops parameter to dump a specific
or multiple trace instances:
- ftrace_dump_on_oops=0: as before -- don't dump
- ftrace_dump_on_oops[=1]: as before -- dump the global trace buffer
on all CPUs
- ftrace_dump_on_oops=2 or =orig_cpu: as before -- dump the global
trace buffer on CPU that triggered the oops
- ftrace_dump_on_oops=<instance_name>: new behavior -- dump the
tracing instance matching <instance_name>
- ftrace_dump_on_oops[=2/orig_cpu],<instance1_name>[=2/orig_cpu],
<instrance2_name>[=2/orig_cpu]: new behavior -- dump the global trace
buffer and multiple instance buffer on all CPUs, or only dump on CPU
that triggered the oops if =2 or =orig_cpu is given
Also, the sysctl node can handle the input accordingly.

The second parameter of __assign_rel_str() is no longer used. It can be removed.
Note, the only real users of rel_string is user events. This code is just
in the sample code for testing purposes.
This makes __assign_rel_str() different than __assign_str() but that's
fine. __assign_str() is used over 700 places and has a larger impact. That

Running the ftrace selftests caused the ring buffer mapping test to fail.
Investigating, I found that the snapshot counter would be incremented
every time a snapshot trigger was added, even if that snapshot trigger
failed.
# cd /sys/kernel/tracing
# echo "snapshot" > events/sched/sched_process_fork/trigger
# echo "snapshot" > events/sched/sched_process_fork/trigger
-bash: echo: write error: File exists
That second one that fails increments the snapshot counter but doesn't
decrement it. It needs to be decremented when the snapshot fails.

Running the ftrace selftests caused the ring buffer mapping test to fail.
Investigating, I found that the snapshot counter would be incremented
every time a tracer that uses the snapshot is enabled even if the snapshot
was used by the previous tracer.
That is:
# cd /sys/kernel/tracing
# echo wakeup_rt > current_tracer
# echo wakeup_dl > current_tracer
# echo nop > current_tracer
would leave the snapshot counter at 1 and not zero. That's because the
enabling of wakeup_dl would increment the counter again but the setting
the tracer to nop would only decrement it once.
Do not arm the snapshot for a tracer if the previous tracer already had it
armed.

The TRACE_EVENT macros has some dependency if a __string() field is NULL,
where it will save "(null)" as the string. This string is also used by
__assign_str(). It's better to create a single macro instead of having
something that will not be caught by the compiler if there is an
unfortunate typo.

The TRACE_EVENT() macro handles dynamic strings by having:
TP_PROTO(struct some_struct *s),
TP_ARGS(s),
TP_STRUCT__entry(
__string(my_string, s->string)
),
TP_fast_assign(
__assign_str(my_string, s->string);
)
TP_printk("%s", __get_str(my_string))
There's even some code that may call a function helper to find the
s->string value. The problem with the above is that the work to get the
s->string is done twice. Once at the __string() and again in the
__assign_str().
The length of the string is calculated via a strlen(), not once, but
twice. Once during the __string() macro and again in __assign_str(). But
the length is actually already recorded in the data location and here's no
reason to call strlen() again.
Just use the saved length that was saved in the __string() code for the
__assign_str() code.

Note, this also means that the second parameter of __assign_str() isn't
even used anymore, and may be removed in the future.

The TP_STRUCT__entry that gets assigned the region name, or an
empty string if no region is present, is erroneously initialized
to the cxl_region pointer. It needs to be properly initialized
otherwise it's length is wrong and garbage chars can appear in
the kernel trace output: /sys/kernel/tracing/trace
The bad initialization was due in part to a naming conflict with
the parameter: struct cxl_region *region. The field 'region' is
already exposed externally as the region name, so changing that
to something logical, like 'region_name' is not an option. Instead
rename the internal only struct cxl_region to the commonly used
'cxlr'.
Impact is that tooling depending on that trace data can miss
picking up a valid event when searching by region name. The
TP_printk() output, if enabled, does emit the correct region
names in the dmesg log.
This was found during testing of the cxl-list option to report
media-errors for a region.

The __string() and __assign_str() helper macros of the TRACE_EVENT() macro
are going through some optimizations where only the source string of
__string() will be used and the __assign_str() source will be ignored and
later removed.
To make sure that there's no issues, a new check is added between the
__string() src argument and the __assign_str() src argument that does a
strcmp() to make sure they are the same string.
The hclgevf trace events have:
__assign_str(devname, &hdev->nic.kinfo.netdev->name);
Which triggers the warning:
hclgevf_trace.h:34:39: error: passing argument 1 of ‘strcmp’ from incompatible pointer type [-Werror=incompatible-pointer-types]
34 | __assign_str(devname, &hdev->nic.kinfo.netdev->name);
[..]
arch/x86/include/asm/string_64.h:75:24: note: expected ‘const char *’ but argument is of type ‘char (*)[16]’
75 | int strcmp(const char *cs, const char *ct);
| ~~~~~~~~~~~~^~
Because __assign_str() now has:
WARN_ON_ONCE(__builtin_constant_p(src) ? \
strcmp((src), __data_offsets.dst##_ptr_) : \
(src) != __data_offsets.dst##_ptr_); \
The problem is the '&' on hdev->nic.kinfo.netdev->name. That's because
that name is:
char name[IFNAMSIZ]
Where passing an address '&' of a char array is not compatible with strcmp().
The '&' is not necessary, remove it.

I'm working on restructuring the __string* macros so that it doesn't need
to recalculate the string twice. That is, it will save it off when
processing __string() and the __assign_str() will not need to do the work
again as it currently does.
Currently __string_len(item, src, len) doesn't actually use "src", but my
changes will require src to be correct as that is where the __assign_str()
will get its value from.
The event class nfsd_clid_class has:
__string_len(name, name, clp->cl_name.len)
But the second "name" does not exist and causes my changes to fail to
