I have to check, whether the priority is propagated when the softirq is
blocked on a lock. If not its a bug and has to be fixed.

I think the simplest solution would be to add

if (p->blocked_on)
wake_up_process(p);

in __setscheduler().


Except that wake_up_process calls try_to_wakeup which grabs the runqueue
lock, which unfortunately is already held when __setscheduler is called.


Yeah, I saw. Move it out in setscheduler() then. I'll try to fix it, but I am not sure I can make a test if it works.
