Message-Id: <20250120082951.1423804-4-houtao@huaweicloud.com> Date: Mon, 20 Jan 2025 16:29:48 +0800 From: Hou Tao <houtao@...weicloud.com> To: dm-devel@...ts.linux.dev Cc: linux-kernel@...r.kernel.org, Alasdair Kergon <agk@...hat.com>, Mike Snitzer <snitzer@...nel.org>, Mikulas Patocka <mpatocka@...hat.com>, Ignat Korchagin <ignat@...udflare.com>, houtao1@...wei.com Subject: [PATCH 3/6] dm-crypt: use bi_sector in bio when initialize integrity seed From: Hou Tao <houtao1@...wei.com> bio->bi_iter.bi_sector has already been initialized when initialize the integrity seed in dm_crypt_integrity_io_alloc(). There is no need to calculate it again. Therefore, use the helper bip_set_seed() to initialize the seed and pass bi_iter.bi_sector to it instead.
