From 2f8c28d0d97313edc36d62cbd505019f36111fd5 Mon Sep 17 00:00:00 2001 From: Hou Tao Date: Mon, 20 Jan 2025 16:29:48 +0800 Subject: [PATCH] dm-crypt: use bi_sector in bio when initialize integrity seed 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. Mikulas: We can't use bip_set_seed because it doesn't compile without CONFIG_BLK_DEV_INTEGRITY.
