Pull exfat updates from Namjae Jeon:
"A set of exfat fixes covering shared writable mappings, entry error
handling, allocation cleanup, FITRIM bounds, and locking:
- Fix valid_size extension over shared writable mappings by lazily
zeroing page-cache gaps and ensuring racing stores cannot be
overwritten or extend beyond valid_size
- Clean up partially written directory entries on add-entry failure
and safely free new directory clusters
- Free a newly allocated directory cluster when zeroing it fails
- Write the destination entry before removing the source entry during
rename, preserving the source if the destination write fails
- Keep FITRIM within the requested range, even when the free-space
search wraps around the allocation bitmap
- Fix truncated FS_IOC_GETFSLABEL results by passing the destination
buffer size in bytes to the UTF-16-to-NLS conversion
- Fix overflow in the cluster-to-dentry calculation, which could
cause readdir to stop early on large volumes
- Replace the per-inode truncate_lock with inode_lock, using shared
locking in bmap to serialize against concurrent truncation
- Update the exfat mailing list address in MAINTAINERS"

Pull perf tools updates from Namhyung Kim:
"perf c2c:
- Add 'function view' in perf c2c report TUI (switched by pressing
'TAB' in the cacheline view) to organize samples around functions
rather than cachelines in 3-level hierarchy:
Level 1: Read-side function (sorted by estimated Cycles %)
Level 2: Contending writer functions (sorted by Store count)
Level 3: Shared cacheline addresses
Users can navigate the entries and fold/unfold using 'e' key. An
example output would look like below:

python module support:
- Extend "perf" python module so that it can be fully functional. The
goal is to run scripts directly, not by 'perf script' command. This
would give better performance as well as more control to build
standalone programs with UI.
- Add LiveSession helper (perf_live.py) to enable live event
collection directly from Python using perf.evlist and
perf.parse_events.
perf stat:
- Add --hide-zero-events option to suppress zero-count events
- Reject conflicting --field-separator and --json-output options
- Fix duplicate event output with --for-each-cgroup
perf sched latency:
- Add -H/--histogram and --hist-mode (log|linear) options to show
scheduler wait latency histograms
- Add --time option to filter analysis by time span in 'perf sched
latency'
ARM CoreSight:
- Synthesize callchains for instruction samples from CoreSight trace
using thread stack ('--itrace=g...')
- Support call indentation ('perf script -F +callindent') to display
call depth hierarchy on branch samples
- Decode ETE (Embedded Trace Extension) exception packets
Build system:
- Add 'make install-build-deps' target to install required packages
- Parallelize JSON and metric pre-computation in jevents.py for
faster builds
Vendor event/metric updates:
- Add Intel Nova Lake events and update tables for existing models
- Update AMD Zen 5 and Zen 6 core events
- Update Arm64 Tegra410 metrics and PowerPC hcalls
Internal changes and fixes:
- Harden trace-event and synthetic event parsing against corrupted

When boot instance creation fails, the kernel incorrectly logs "(null)"
as the instance name because strsep() consumes curr_str entirely during
parsing.
Print the properly parsed name variable instead. And while at it log
the error code.

i2c: rust: mark I2cAdapter methods as inline
A single cleanup for the Rust I2C abstractions, targeting 7.3.
`I2cAdapter::get`, `inc_ref`, and `dec_ref` are trivial wrappers around
`i2c_get_adapter`/`i2c_put_adapter` and were showing up as their own
symbols in the build. Mark them `#[inline]` so they get folded into
their callers instead.

i2c: rust: mark I2cAdapter methods as inline
|
|
When building the kernel using llvm-19.1.7-rust-1.85.0-x86_64, the
following symbols are generated:
$ nm vmlinux | grep ' _R'.*I2cAdapter | rustfilt
ffffffff817ff380 T <kernel::i2c::I2cAdapter>::get
ffffffff817ff400 T <kernel::i2c::I2cAdapter as kernel::sync::aref::AlwaysRefCounted>::dec_ref
ffffffff817ff3e0 T <kernel::i2c::I2cAdapter as kernel::sync::aref::AlwaysRefCounted>::inc_ref
However, these Rust symbols are trivial wrappers around the
`i2c_get_adapter` and `i2c_put_adapter` functions. It doesn't make sense
to go through a trivial wrapper for these functions.

Sync common.bpf.h, compat.bpf.h and compat.h with the scx repo, which
accumulated the following:
- __COMPAT_read_enum() can now recover 64-bit scx enum values from kernel
BTF generated without BTF_KIND_ENUM64 support (pahole < 1.24 or
--skip_encoding_btf_enum64, e.g. COS/GKE kernels), substituting values
from the build-time vmlinux.h cross-checked against the low 32 bits the
kernel does provide.
- is_migration_disabled() no longer assumes the BPF prolog always disables
migration. Since 8e4f0b1ebcf2 ("bpf: use rcu_read_lock_dont_migrate() for
trampoline.c") the prolog only does so under CONFIG_PREEMPT_RCU, so the
old current-task test under-reported on v6.18+ !PREEMPT_RCU kernels. A
runtime probe on bpf_scx_reg() handles older kernels with backported
trampoline behavior.
- __COMPAT_scx_bpf_dsq_peek() is gated behind kernel v7.1 where 2f2ea7709266
("sched_ext: Use dsq->first_task instead of list_empty() in
dispatch_enqueue() FIFO-tail") fixed the kfunc spuriously returning NULL
on non-empty FIFO DSQs, and the new
scx_bpf_reenqueue_local_from_anywhere() provides a callable-from-anywhere
reenqueue which prefers the generic scx_bpf_dsq_reenq(). Both were first
posted by Gavin Guo and Changwoo Min and are picked up here with the
review feedback folded in.
- __COMPAT_scx_bpf_cpu_curr() and the scx_bpf_cpu_rq() declaration are
restored. Schedulers built from these headers still run on pre-v6.18
kernels where scx_bpf_cpu_curr() does not resolve and the scx_bpf_cpu_rq()
fallback still exists.
- scx_clock_task() and scx_clock_pelt() document their stale-read behavior
for remote idle CPUs under NO_HZ_IDLE.

Regenerate enum_defs.autogen.h against the current tree, picking up the
dispatch verdict enums and dropping the marker for the removed
SCX_RQ_IN_BALANCE. Add enums_abi.autogen.h, a table of 64-bit scx enumerator
values generated from vmlinux.h, used as the substitution source when the
running kernel's BTF truncates 64-bit enum values to 32 bits.

F2FS writes long symlink data with page_symlink() and then flushes the
symlink mapping to reduce the chance of exposing a broken symlink.
That flush result is currently ignored. If the writeback fails, symlink()
still returns success even though the symlink is not durable and the same
operation can already surface -EIO through syncfs().
Return the writeback error to userspace and skip the dirsync flush once the
symlink data flush has failed.

In f2fs_rename() and f2fs_unlink(), directly returning -EPERM when
encountering a device aliasing file bypasses the cleanup path.
Fix this by setting err to -EPERM and jumping to the proper cleanup

In v1, Rosen pointed out that the import of "mpc5200_dma.h" is actually

be changed to 'depends on'.
This resolves all 3 unmet dependencies.

layer while trying to enable a DAPM path, while the device
is still being attached, -EBUSY error will be thown by
regmap_read and regmap_udpate_bits. Because the regmap will
be in cache only mode. Add default values for these registers
so that, the cached values are returned instead of error.
* Also remove writing default values once again for first
