Subject: [PATCH v5 0/3] locking/rwsem: Add DEBUG_RWSEMS & restructure lock debugging menu
Date: Fri, 30 Mar 2018 17:27:57 -0400	[thread overview]
Message-ID: <1522445280-7767-1-git-send-email-longman@redhat.com> (raw)

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
