dm delay: use per-bio data instead of a mempool and slab cache
Starting with commit c0820cf ("dm: introduce per_bio_data"), device mapper has the capability to pre-allocate a target-specific structure with the bio. This patch changes dm-delay to use this facility instead of a slab cache and mempool. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
