# HEAD: 2b9d9e0a9ba0e24cb9c78336481f0ed8b2bc1ff2 locking/mutex: Clarify that mutex_unlock(), and most other sleeping locks, can still use the lock object after it's unlocked
Locking changes for v6.8:
- 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
Thanks,
Ingo
