From: Peter Zijlstra Date: Thu, 16 Oct 2008 11:44:57 +0000 (+0200) Subject: block: move q->unplug_work initialization X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=713ada9ba94f2ad874cffd074b83e3dc681ca82f;p=linux-beck.git block: move q->unplug_work initialization 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*().
