[PATCH] CFQ io scheduler: scheduler switch oops
If cfq is managing a queue and a new scheduler is later selected, it is
possible for the cfqd unplug_work work to be queued after the kblockd
work struct has been flushed. The problem is the ordering of
cfq_shutdown_timer_wq() and blk_put_queue() in cfq_put_cfqd(). The
latter may rearm the work, leaving cfq_kick_queue() with dead data.
