Subject: [GIT PULL] locking changes for v6.13
Linus,
Please pull the latest locking/core Git tree from:

# HEAD: 3b49a347d751553b1d1be69c8619ae2e85fdc28d locking/Documentation: Fix grammar in percpu-rw-semaphore.rst
Locking changes for v6.13 are:
- lockdep:
- Enable PROVE_RAW_LOCK_NESTING with PROVE_LOCKING (Sebastian Andrzej Siewior)
- Add lockdep_cleanup_dead_cpu() (David Woodhouse)
- futexes:
- Use atomic64_inc_return() in get_inode_sequence_number() (Uros Bizjak)
- Use atomic64_try_cmpxchg_relaxed() in get_inode_sequence_number() (Uros Bizjak)
- RT locking:
- Add sparse annotation PREEMPT_RT's locking (Sebastian Andrzej Siewior)
- spinlocks:
- Use atomic_try_cmpxchg_release() in osq_unlock() (Uros Bizjak)
- atomics:
- x86: Use ALT_OUTPUT_SP() for __alternative_atomic64() (Uros Bizjak)
- x86: Use ALT_OUTPUT_SP() for __arch_{,try_}cmpxchg64_emu() (Uros Bizjak)
- KCSAN, seqlocks:
- Support seqcount_latch_t (Marco Elver)
- <linux/cleanup.h>:
- Add if_not_cond_guard() conditional guard helper (David Lechner)
- Adjust scoped_guard() macros to avoid potential warning (Przemek Kitszel)
- Remove address space of returned pointer (Uros Bizjak)
- WW mutexes:
- locking/ww_mutex: Adjust to lockdep nest_lock requirements (Thomas Hellström)
- Rust integration:
- Fix raw_spin_lock initialization on PREEMPT_RT (Eder Zulian)
- miscellaneous cleanups & fixes:
- lockdep: Fix wait-type check related warnings (Ahmed Ehab)
- lockdep: Use info level for initial info messages (Jiri Slaby)
- spinlocks: Make __raw_* lock ops static (Geert Uytterhoeven)
- pvqspinlock: Convert fields of 'enum vcpu_state' to uppercase (Qiuxu Zhuo)
- iio: magnetometer: Fix if () scoped_guard() formatting (Stephen Rothwell)
- rtmutex: Fix misleading comment (Peter Zijlstra)
- percpu-rw-semaphores: Fix grammar in percpu-rw-semaphore.rst (Xiu Jianfeng)
Thanks,
Ingo
