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