[GIT PULL] [PATCH 0/9] Locking changes for v6.17

[Boqun Feng]

Hi Ingo & Peter,

Please pull the lockdep changes for v6.17 into tip. One thing to notice
is that I would like to add Breno Leitao's workaround in
lockdep_unregister_key(), since the alternative requires hazptr and I'm
not near to get it done. I added comments explaining this and left a
TODO there, and I will replace it once the shazptr patch is in a good
shape. Peter, if you have any concern about it, either we can drop the
patch #9 or I can create another tag. Thanks!

The following changes since commit 7ff495e26a39f3e7a3d4058df59b5b6d6f943cab:

  local_lock: Move this_cpu_ptr() notation from internal to main header (2025-06-30 17:45:35 +0200)

  lockdep: Speed up lockdep_unregister_key() with expedited RCU synchronization (2025-07-14 21:57:29 -0700)

----------------------------------------------------------------
Locking changes for v6.17:

- General
  - Mark devm_mutex_init() as __must_check
  - Add #[must_use] to Lock::try_lock()
  - Remove OWNER_SPINNABLE in rwsem
  - Remove redundant #ifdefs in mutex
- Lockdep
  - Avoid returning struct in lock_stats()
  - Change `static const` into enum for LOCKF_*_IRQ_*
  - Temporarily use synchronize_rcu_expedited() in
    lockdep_unregister_key() to speed things up.

----------------------------------------------------------------

Regards,
Boqun
