Linus Torvalds 3e71f0167b Locking changes for v6.1:
- Disable preemption in rwsem_write_trylock()'s attempt to
    take the rwsem, to avoid RT tasks hogging the CPU, which
    managed to preempt this function after the owner has
    been cleared but before a new owner is set. Also add
    debug checks to enforce this.
 
  - Add __lockfunc to more slow path functions and add
    __sched to semaphore functions.
 
  - Mark spinlock APIs noinline when the respective CONFIG_INLINE_SPIN_*
    toggles are disabled, to reduce LTO text size.
 
  - Print more debug information when lockdep gets confused
    in look_up_lock_class().
 
  - Improve header file abuse checks.
 
  - Misc cleanups
