[PATCH v5 0/7] add mutex wait/wound/style style locks
From: Maarten Lankhorst
Date: Thu Jun 20 2013 - 07:32:25 EST
Changes since v4:
- Some documentation cleanups.
- Added a lot more tests to cover all the DEBUG_LOCKS_WARN_ON cases.
- Added EDEADLK tests.
- Split off the normal mutex tests to a separate patch.
- Added a patch to not allow tests to fail that succeed with PROVE_LOCKING enabled.
