Revision 713ada9ba94f2ad874cffd074b83e3dc681ca82f authored by Peter Zijlstra on 16 October 2008, 11:44:57 UTC, committed by Jens Axboe on 17 October 2008, 06:46:57 UTC
modprobe loop; rmmod loop effectively creates a blk_queue and destroys it
which results in q->unplug_work being canceled without it ever being
initialized.

Therefore, move the initialization of q->unplug_work from
blk_queue_make_request() to blk_alloc_queue*().
