Subject: [PATCH 06/19] dm-crypt: remove clone_init
Date:   Mon, 24 Jan 2022 10:10:54 +0100
Message-Id: <20220124091107.642561-7-hch@lst.de>
In-Reply-To: <20220124091107.642561-1-hch@lst.de>

Just open code it next to the bio allocations, which saves a few lines
of code, prepares for future changes and allows to remove the duplicate
bi_opf assignment for the bio_clone_fast case in kcryptd_io_read.
