Subject: [PATCH 1/5] dm-mpath: remove annoying message of 'blk_get_request() returned -11'
Date: Sat, 30 Sep 2017 19:46:48 +0800 [thread overview]
Message-ID: <20170930114652.32441-2-ming.lei@redhat.com> (raw)
In-Reply-To: <20170930114652.32441-1-ming.lei@redhat.com>
It is very normal to see allocation failure, so not necessary
to dump it and annoy people.
