3.19.8-ckt1 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Oded Gabbay <oded.gabbay@xxxxxxxxx>
commit 1e5ec956a057585adaa1365615c82810b2f5356f upstream.
Sometimes we might unregister process that have queues, because we couldn't
preempt the queues. Until now we blocked it with BUG_ON but instead just
print it as debug.
