    Subject[patch 08/54] make freezeable workqueues singlethread
    -stable review patch.  If anyone has any objections, please let us know.
    ---------------------

    From: Oleg Nesterov <oleg@tv-sign.ru>

    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.
