dm: call blk_queue_split() to impose device limits on bios
Otherwise the incoming bios, of various types, won't be shaped based on the DM device's advertised limits. Depends-on: af67c31fba ("blk: remove bio_set arg from blk_queue_split()") Fixes: 744889b7cb ("block: don't deal with discard limit in blkdev_issue_discard()") Cc: stable@vger.kernel.org Signed-off-by: Mike Snitzer <snitzer@redhat.com>
