Subject: [dm-devel] [PATCH 22/30] rbd: use blk_mq_alloc_disk and blk_cleanup_disk
Date: Wed,  2 Jun 2021 09:53:37 +0300	[thread overview]
Message-ID: <20210602065345.355274-23-hch@lst.de> (raw)
In-Reply-To: <20210602065345.355274-1-hch@lst.de>

Use blk_mq_alloc_disk and blk_cleanup_disk to simplify the gendisk and
request_queue allocation.
