History
Linus Torvalds 9eef023345 These are the v5.12 updates for the locking subsystem: 
- Core locking primitives updates:
 
     - Remove mutex_trylock_recursive() from the API - no users left
     - Simplify + constify the futex code a bit
 
  - Lockdep updates:
 
     - Teach lockdep about local_lock_t
     - Add CONFIG_DEBUG_IRQFLAGS=y debug config option to check for
       potentially unsafe IRQ mask restoration patterns. (I.e.
       calling raw_local_irq_restore() with IRQs enabled.)
     - Add wait context self-tests
     - Fix graph lock corner case corrupting internal data structures
     - Fix noinstr annotations
 
  - LKMM updates:
 
     - Simplify the litmus tests
     - Documentation fixes
 
  - KCSAN updates:
 
     - Re-enable KCSAN instrumentation in lib/random32.c
 
  - Misc fixes:
 
     - Don't branch-trace static label APIs
     - DocBook fix
     - Remove stale leftover empty file
