Subject: [PATCH v3 19/19] block: mark bio_add_page as __must_check
Date: Wed, 19 Apr 2023 16:09:29 +0200 [thread overview]
Message-ID: <20230419140929.5924-20-jth@kernel.org> (raw)
In-Reply-To: <20230419140929.5924-1-jth@kernel.org>
From: Johannes Thumshirn <johannes.thumshirn@wdc.com>
Now that all users of bio_add_page check for the return value, mark
bio_add_page as __must_check.
