[PATCH v5 0/3] locking/rwsem: Add DEBUG_RWSEMS & restructure lock debugging menu

From: Waiman Long
Date: Fri Mar 30 2018 - 17:28:16 EST


v5:
- Break patch 2 into 2 separate patches to make them easier to review.

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 (3):
locking/rwsem: Add DEBUG_RWSEMS to look for lock/unlock mismatches
lib/Kconfig.debug: Add LOCK_DEBUGGING_SUPPORT to make it more readable
lib/Kconfig.debug: Restructure the lock debugging menu
