Hi Ingo,
Looks like the BKL is a little more complicated than what I first sent.
I've been analyzing the logic and found that there's a point in time
where the BKL->P1->L1->P2->BKL can exist without any of the spinlocks
protecting it. That is after P1 blocks on L1 but before it schedules
out and

I just found another deadlock in the pi_lock logic. The PI logic is
very dependent on the P1->L1->P2->L2->P3 order. But our good old friend
is back, the BKL.
Since the BKL is let go and regrabbed even if a task is grabbing another
lock, it messes up the order. For example, it can do the
