[PATCH v4 0/2] locking/rwsem: Add DEBUG_RWSEMS

[Waiman Long]

v4:
 - Auto select DEBUG_RWSEMS & DEBUG_WW_MUTEX_SLOWPATH if PROVE_LOCKING
 - Modify patch 2 to do a restructuring of the lock debugging menu.

v3:
 - Add a new patch which adds a master LOCK_DEBUGGING option to turn
   on all lock debugging.

v2:
 - Fix typo in up_read_non_owner().

This patchset enhances lock debugging by adding rwsem lock/unlock
mismatches checking and restructure the lock debugging menu to make it
easier to select options that are likely to be most frequently used.

Waiman Long (2):
  locking/rwsem: Add DEBUG_RWSEMS to look for lock/unlock mismatches
  locking/debug: Restructure the lock debugging menu
