If anyone has any objections, please let me know. ------------------ From: Oded Gabbay 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.
