Subject: [PATCH] dm thin: remove needless request_queue NULL pointer check
Date: Fri, 19 Mar 2021 08:11:13 +0000 [thread overview]
Message-ID: <20210319081113.16916-1-vulab@iscas.ac.cn> (raw)
Since commit ff9ea323816d ("block, bdi: an active gendisk always has a
request_queue associated with it") the request_queue pointer returned
from bdev_get_queue() shall never be NULL.
