From c2a9331c62216e222a08de8dd58559367fef0af6 Mon Sep 17 00:00:00 2001 From: Date: Tue, 12 Apr 2005 16:38:09 -0500 Subject: updates for CFQ oops fix - add a comment to the device structure that the device_busy field is now protected by the request_queue->queue_lock - null out sdev->request_queue after the queue is released to trap any (and there shouldn't be any) use after the queue is freed.
