Linus,

Please pull the latest locking/core Git tree from:

   # HEAD: ba28549bad8ab2b09264ebc8c2ca24af3537ee52 Merge tag 'lockdep-for-tip.2025.07.16' of git://git.kernel.org/pub/scm/linux/kernel/git/boqun/linux into locking/core

Locking updates for v6.16:

Locking primitives:

  - Mark devm_mutex_init() as __must_check and fix drivers
    that didn't check the return code. (Thomas Weißschuh)

  - Reorganize <linux/local_lock.h> to better expose the
    internal APIs to local variables. (Sebastian Andrzej Siewior)

  - Remove OWNER_SPINNABLE in rwsem (Jinliang Zheng)

  - Remove redundant #ifdefs in the mutex code (Ran Xiaokai)

Lockdep:

  - Avoid returning struct in lock_stats() (Arnd Bergmann)

  - Change `static const` into enum for LOCKF_*_IRQ_*
    (Arnd Bergmann)

  - Temporarily use synchronize_rcu_expedited() in
    lockdep_unregister_key() to speed things up.
    (Breno Leitao)

Rust runtime:

  - Add #[must_use] to Lock::try_lock() (Jason Devers)

 Thanks,

	Ingo
