Linus,

# HEAD: 76e64c73db9542ff4bae8a60f4f32e38f3799b95 locking/lockdep: Print more debug information - report name and key when look_up_lock_class() got confused
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
Thanks,
Ingo
