dm rq: cleanup leftover code from recently removed q->mq_ops branching (34743bfd) · Commits · 戴 / test

When commit ("dm: remove legacy request-based IO path") removed some q->mq_ops branching from map_request() it left in place a goto that was only needed if that branching (and conditional 'r' assignment) existed. Now that the branching is gone map_request()'s goto can be removed too. Signed-off-by:
