Added parentheses around sizeof to make the expression clearer
and improve readability. This change has no functional impact.

The comment was correct, but `checkpatch` script flagged it with a warning
as shown in the output section. The comment is slightly modified
to improve readability, which also suppresses the warning.

Pull vfs fixes from Christian Brauner:
"fuse:
- Prevent opening of non-regular backing files.
Fuse doesn't support non-regular files anyway.
- Check whether copy_file_range() returns a larger size than
requested.
- Prevent overflow in copy_file_range() as fuse currently only
supports 32-bit sized copies.
- Cache the blocksize value if the server returned a new value as
inode->i_blkbits isn't modified directly anymore.
- Fix i_blkbits handling for iomap partial writes.
By default i_blkbits is set to PAGE_SIZE which causes iomap to mark
the whole folio as uptodate even on a partial write. But fuseblk
filesystems support choosing a blocksize smaller than PAGE_SIZE
risking data corruption. Simply enforce PAGE_SIZE as blocksize for
fuseblk's internal inode for now.
- Prevent out-of-bounds acces in fuse_dev_write() when the number of
bytes to be retrieved is truncated to the fc->max_pages limit.
virtiofs:
- Fix page faults for DAX page addresses.
Misc:
- Tighten file handle decoding from userns.
Check that the decoded dentry itself has a valid idmapping in the
user namespace.
- Fix mount-notify selftests.
- Fix some indentation errors.
- Add an FMODE_ flag to indicate IOCB_HAS_METADATA availability.
This will be moved to an FOP_* flag with a bit more rework needed
for that to happen not suitable for a fix.
- Don't silently ignore metadata for sync read/write.
- Don't pointlessly log warning when reading coredump sysctls"

The minimum supported GCC version is 8.1, which supports flag output operands
and always defines __GCC_ASM_FLAG_OUTPUTS__ macro.
Remove code depending on __GCC_ASM_FLAG_OUTPUTS__ and use the "=@ccCOND" flag
output operand directly.
Use the equivalent "=@ccz" instead of "=@cce" flag output operand for
CMPXCHG8B and CMPXCHG16B instructions. These instructions set a single flag
bit - the Zero flag - and "=@ccz" is used to distinguish the CC user from
comparison instructions, where set ZERO flag indeed means that the values are
equal.

devmem test fails on NIPA. Most likely we get skb(s) with readable
frags (why?) but the failure manifests as an OOM. The OOM happens
because ncdevmem spams the following message:
recvmsg ret=-1
recvmsg: Bad address
As of today, ncdevmem can't deal with various reasons of EFAULT:
- falling back to regular recvmsg for non-devmem skbs
- increasing ctrl_data size (can't happen with ncdevmem's large buffer)
Exit (cleanly) with error when recvmsg returns EFAULT. This should at
least cause the test to cleanup its state.

Add the ability to dump BPF program instructions directly from veristat.
Previously, inspecting a program required separate bpftool invocations:
one to load and another to dump it, which meant running multiple
commands.
During active development, it's common for developers to use veristat
for testing verification. Integrating instruction dumping into veristat
reduces the need to switch tools and simplifies the workflow.
By making this information more readily accessible, this change aims
to streamline the BPF development cycle and improve usability for
developers.
This implementation leverages bpftool, by running it directly via popen
to avoid any code duplication and keep veristat simple.

James Clark caught that the BUILD_NONDISTRO=1 build with libbfd was
broken due to an update to the read_build_id function adding a
blocking argument. Add support for this argument by first opening the
file blocking or non-blocking, then switching from bfd_openr to
bfd_fdopenr and passing the opened fd. bfd_fdopenr closes the fd on
error and when bfd_close are called.

commit edf2cadf01e8f ("perf test: add test for BPF metadata collection")
fails consistently on the version string check. The perf version
string on some of the constant integration test machines contains
characters with special meaning in grep's extended regular expression
matching algorithm. The output of perf version is:
# perf version
perf version 6.17.0-20250814.rc1.git20.24ea63ea3877.63.fc42.s390x+git
#
and the '+' character has special meaning in egrep command.
Also the use of egrep is deprecated.
Change the perf version string check to fixed character matching
and get rid of egrep's warning being deprecated. Use grep -F instead.
Output before:
# perf test -F 102
Checking BPF metadata collection
egrep: warning: egrep is obsolescent; using grep -E
Basic BPF metadata test [Failed invalid output]
102: BPF metadata collection test : FAILED!
#
Output after:
# perf test -F 102

The "Parsing of PMU event table metrics with fake PMUs" will test
metrics on machines/models that may be missing a PMU, in such a case
the fake_pmu should be used to avoid errors.
Metrics that get the cpumask from a different PMU, such as
"tsc/cpu=cpu_atom/", also need to be resilient in this test.
The parse_events_state fake_pmu is set when missing PMUs should be
ignored.
So that it can be queried, pass it to the config term functions, as well
as to get_config_cpu, then ignore failures when fake_pmu is set.
Some minor code refactoring to cut down on the indent and remove some
redundant checks.
Fixes: bd741d80dc65922c ("perf parse-events: Allow the cpu term to be a PMU or CPU range")

Remove unused 'elf' and 'path' parameters from parse_usdt_note function
signature. These parameters are not referenced within the function body
and only add unnecessary complexity.
The function only requires the note header, data buffer, offsets, and
output structure to perform USDT note parsing.
Update function declaration, definition, and the single call site in
collect_usdt_targets() to match the simplified signature.
This is a safe internal cleanup as parse_usdt_note is a static function.

Filtering pid_tgid is meanlingless when the current task is preempted by
an interrupt.
To address this, introduce 'bpf_in_interrupt()' helper function, which
allows BPF programs to determine whether they are executing in interrupt
context.
'get_preempt_count()':
* On x86, '*(int *) bpf_this_cpu_ptr(&__preempt_count)'.
* On arm64, 'bpf_get_current_task_btf()->thread_info.preempt.count'.
Then 'bpf_in_interrupt()' will be:
* If !PREEMPT_RT, 'get_preempt_count() & (NMI_MASK | HARDIRQ_MASK
| SOFTIRQ_MASK)'.
* If PREEMPT_RT, '(get_preempt_count() & (NMI_MASK | HARDIRQ_MASK))
| (bpf_get_current_task_btf()->softirq_disable_cnt & SOFTIRQ_MASK)'.
As for other archs, it can be added support by updating
'get_preempt_count()'.
