       on x86 (Uros Bizjak)
 
     - mutexes: extend debug checks in mutex_lock() (Yunhui Cui)
 
     - Misc cleanups (Uros Bizjak)
 
   Lockdep:
 
     - Fix might_fault() lockdep check of current->mm->mmap_lock (Peter Zijlstra)
 
     - Don't disable interrupts on RT in disable_irq_nosync_lockdep.*()
       (Sebastian Andrzej Siewior)
 
     - Disable KASAN instrumentation of lockdep.c (Waiman Long)
 
     - Add kasan_check_byte() check in lock_acquire() (Waiman Long)
 
     - Misc cleanups (Sebastian Andrzej Siewior)
 
   Rust runtime integration:

     - sync: Add accessor for the lock behind a given guard (Alice Ryhl)
     - sync: condvar: Add wait_interruptible_freezable() (Alice Ryhl)
     - sync: lock: Add an example for Guard:: Lock_ref() (Boqun Feng)
 
   Split-lock detection feature (x86):
 
     - Fix warning mode with disabled mitigation mode (Maksim Davydov)
