Subject: make freezeable workqueues singlethread
From: Oleg Nesterov <oleg@xxxxxxxxxx>
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.
