- Subject: PP mutex and SCHED_OTHER
If a thread with SCHED_OTHER priority was going to take a PP mutex, it
always fails because __pthread_tpp_change_priority() tries to change
its priority without changing its sched policy.
Is this a spec, or design, or bug?
It is unclear for me if non-FIFO thread can take PP mutex or not.
