Subject: [PATCH v3 0/2] locking/debug: Add DEBUG_RWSEMS & LOCK_DEBUGGING
Date: Tue, 27 Mar 2018 17:38:08 -0400 [thread overview]
Message-ID: <1522186690-10526-1-git-send-email-longman@redhat.com> (raw)
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
