However, it does seem a bit silly, as we end up dropping and-reaquiring the sched lock quite a few times:
That's why I just asked you to test the concept.. If I know that just aquiring it here is ok, (I presume you tried doing some work like this) that tells me that this code isn't called from some odd place, with the sched lock already set.
(that and code inspection of course..)
Now we know it works we can try optimise it..
I'm going home now for dinner, so if you feel like checking this or something mor optimal in, be my guest :-)
OK, I've checked in the unoptimized fix. Please do optimize it when you get a chance.
Erm, I thought I changd signotify() to require sched_lock and made the second half of psignal() (the whole case statement) lock sched_lock. Did you change that? (To Julian)
