Subject: [PATCH v2 3/7] dm-verity: remove unnecessary condition for verity_fec_finish_io()
Date: Fri, 19 Dec 2025 11:29:05 -0800 [thread overview]
Message-ID: <20251219192909.385494-4-ebiggers@kernel.org> (raw)
In-Reply-To: <20251219192909.385494-1-ebiggers@kernel.org>
Make verity_finish_io() call verity_fec_finish_io() unconditionally,
instead of skipping it when 'in_bh' is true.
Although FEC can't have been done when 'in_bh' is true,
verity_fec_finish_io() is a no-op when FEC wasn't done. An earlier
change also made verity_fec_finish_io() very lightweight when FEC wasn't
done. So it should just be called unconditionally.
