Subject: [PATCH 1/7] block: Add some exports for bcachefs
Date: Thu, 25 May 2023 17:48:16 -0400 [thread overview]
Message-ID: <20230525214822.2725616-2-kent.overstreet@linux.dev> (raw)
In-Reply-To: <20230525214822.2725616-1-kent.overstreet@linux.dev>
From: Kent Overstreet <kent.overstreet@gmail.com>
- bio_set_pages_dirty(), bio_check_pages_dirty() - dio path
- blk_status_to_str() - error messages
- bio_add_folio() - this should definitely be exported for everyone,
it's the modern version of bio_add_page()
