Subject: [PATCH v2 13/14] ext2: replace bh_submit_read() helper with bh_read_locked()
Date:   Thu, 1 Sep 2022 21:35:04 +0800
Message-ID: <20220901133505.2510834-14-yi.zhang@huawei.com>

Precedence: bulk

bh_submit_read() and the uptodate check logic in bh_uptodate_or_lock()
has been integrated in bh_read() helper, so switch to use it directly.
