Mike will give it some testing. I just found out that this patch will explode nicely when the unplug code runs into a contended lock. Then we try to block on that lock and make the rtmutex code unhappy as we are already blocked on something else. So no, it's not a solution to the problem. Sigh. Can you figure out on which lock the stuck thread which did not unplug due to tsk_is_pi_blocked was blocked?
