    dm: remove request-based logic from make_request_fn wrapper · ff36ab34
    Mike Snitzer 提交于
    The old dm_request() method used for q->make_request_fn had a branch for
    request-based DM support but it isn't needed given that
    dm_init_request_based_queue() sets it to the standard blk_queue_bio()
    anyway.
    
    Cleanup dm_init_md_queue() to be DM device-type agnostic and have
    dm_setup_md_queue() properly finish queue setup based on DM device-type
    (bio-based vs request-based).
    
    A followup block patch can be made to remove the export for
    blk_queue_bio() now that DM no longer calls it directly.
