I don't get any print outs of any deadlock detection with many of my

When there is a deadlock down() simply returns instead of blocking
forever.

rt_mutex_slowlock seems to return -EDEADLK even though caller didn't ask
for deadlock detection (detect_deadlock=0). That is bad because then the
caller will not check for it. It ought to simply leave the task blocked.

It only happens with CONFIG_DEBUG_RT_MUTEXES. That one also messes up the
task->pi_waiters as earlier reported.

It just looks like also normal, non-rt tasks are boosting.
