The new PI code covers all synchronization objects in Linux (on
PREEMPT_REALTIME): spinlocks, rwlocks, semaphores and rwsems. Feedback on the design of this code would be welcome, and patches as
well, if you have a better scheme. The code is pretty modular so feel free to experiment with alternative schemes.

I didn't see closure being performed of a possible blocked-owner
dependency chain, but only promotion of the immediate owner. It
is possible for a mutex owner to itself be blocked on another mutex
requiring promotion of the latter mutex owner(s).
