Subject: [PATCH v3 0/2] locking/debug: Add DEBUG_RWSEMS & LOCK_DEBUGGING

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 a master config option to turn on all lock
debugging.

Waiman Long (2):
  locking/rwsem: Add DEBUG_RWSEMS to look for lock/unlock mismatches
  locking/debug: Add a master lock debugging switch
