Subject: [PATCH 1/7] blk-mq: fix use of incorrect goto label in blk_mq_init_queue error path
Date: Wed, 11 Mar 2015 23:56:36 -0400 [thread overview]
Message-ID: <1426132602-34331-2-git-send-email-snitzer@redhat.com> (raw)
In-Reply-To: <1426132602-34331-1-git-send-email-snitzer@redhat.com>
If percpu_ref_init() fails the 'err_hctxs' label should be used instead
of 'err_map'.
