Merge tag 'locking-core-2024-01-08' of git://git./linux/kernel/git/tip/tip

Pull locking updates from Ingo Molar:
 "Lock guards:

   - Use lock guards in the ptrace code

   - Introduce conditional guards to extend to conditional lock
     primitives like mutex_trylock()/mutex_lock_interruptible()/etc.

  lockdep:

   - Optimize 'struct lock_class' to be smaller

   - Update file patterns in MAINTAINERS

  mutexes:

   - Document mutex lifetime rules a bit more"

* tag 'locking-core-2024-01-08' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  locking/mutex: Clarify that mutex_unlock(), and most other sleeping locks, can still use the lock object after it's unlocked
  locking/mutex: Document that mutex_unlock() is non-atomic
  ptrace: Convert ptrace_attach() to use lock guards
  locking/lockdep: Slightly reorder 'struct lock_class' to save some memory
  MAINTAINERS: Add include/linux/lockdep*.h
  cleanup: Add conditional guard support
