Subject: [PATCH RESEND v3 05/13] blk-mq-sched: Rename blk_mq_sched_alloc_{tags -> map_and_rqs}()
Date: Mon, 13 Sep 2021 23:12:22 +0800 [thread overview]
Message-ID: <1631545950-56586-6-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1631545950-56586-1-git-send-email-john.garry@huawei.com>
Function blk_mq_sched_alloc_tags() does same as
__blk_mq_alloc_map_and_request(), so give a similar name to be consistent.
Similarly rename label err_free_tags -> err_free_map_and_rqs.
