cfq_exit_queue() should cancel cfq_data->unplug_work
Spotted by Nick <gentuu@gmail.com>, perhaps explains the first trace in http://bugzilla.kernel.org/show_bug.cgi?id=9180. cfq_exit_queue() should cancel cfqd->unplug_work before freeing cfqd. blk_sync_queue() seems unneeded, removed. Q: why cfq_exit_queue() calls cfq_shutdown_timer_wq() twice? Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
