-stable review patch. If anyone has any objections, please let us know.
---------------------
From: Oleg Nesterov <[email protected]>
It is a known fact that freezeable multithreaded workqueues doesn't like
CPU_DEAD. We keep them only for the incoming CPU-hotplug rework.
Sadly, we can't just kill create_freezeable_workqueue() right now, make
them singlethread.
