See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: linux-btrfs@vger.kernel.org Hi Jens, this series finishes off the bio allocation interface cleanups by dealing with the weirdest member of the famility. bio_kmalloc combines a kmalloc for the bio and bio_vecs with a hidden bio_init call and magic cleanup semantics. This series moves a few callers away from bio_kmalloc and then turns bio_kmalloc into a simple wrapper for a slab allocation of a bio and the inline biovecs. The callers need to manually call bio_init instead with all that entails and the magic that turns bio_put into a kfree goes away as well, allowing for a proper debug check in bio_put that catches accidental use on a bio_init()ed bio.
