Folks, any thoughts on this? Thanks, Davidlohr

[PATCH -tip v2 0/4] rtmutex: Another crack at spin on owner

Changes from v1: - Dropped patch 4 that removed the barrier in the deadlock path. - Added patch 2 (trivial) to use poison.h defines. - sprinkled READ/WRITE_ONCE around lock->owner, even if updated inside the cr. (peterz) - More testing time. This is a followup to proposal sometime ago
