Subject: [PATCH 06/15] blk-mq: remove blk_qc_t_to_tag and blk_qc_t_is_internal
Date: Tue, 27 Apr 2021 18:16:10 +0200 [thread overview]
Message-ID: <20210427161619.1294399-7-hch@lst.de> (raw)
In-Reply-To: <20210427161619.1294399-1-hch@lst.de>
Merge both functions into their only caller to keep the blk-mq tag to
blk_qc_t mapping as private as possible in blk-mq.c.
