Version 4 already?
Small api changes since v3:
- Remove ww_mutex_unlock_single and ww_mutex_lock_single.
- Rename ww_mutex_trylock_single to ww_mutex_trylock.
- Remove separate implementations of ww_mutex_lock_slow*, normal functions can be used. Inline versions still exist for extra debugging, and to annotate.
- Cleanup unneeded memory barriers, add comment to the remaining smp_mb().
Thanks to Daniel Vetter, Rob Clark and Peter Zijlstra for their feedback.
Daniel Vetter (1): mutex: w/w mutex slowpath debugging
Maarten Lankhorst (3): arch: make __mutex_fastpath_lock_retval return whether fastpath succeeded or not. mutex: add support for wound/wait style locks, v5 mutex: Add ww tests to lib/locking-selftest.c. v4
