Linus Torvalds 72b8944f14 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)
