It's already required that the hb lock, i.e. q->lock_ptr is held on
entry. So there is no point for adding hb to the interface. We rather
add "struct spin_lock *lock" to free_pi_state() and hand in
q->lock_ptr from here and &hb2->lock from requeue_pi.
I take the immediate bugfix and strip out this debug stuff for
now. Care to resend this part?
