      dm mpath: add optional "queue_mode" feature · e83068a5
      Mike Snitzer authored
      
      
      Allow a user to specify an optional feature 'queue_mode <mode>' where
      <mode> may be "bio", "rq" or "mq" -- which corresponds to bio-based,
      request_fn rq-based, and blk-mq rq-based respectively.
      
      If the queue_mode feature isn't specified the default for the
      "multipath" target is still "rq" but if dm_mod.use_blk_mq is set to Y
      it'll default to mode "mq".
      
      This new queue_mode feature introduces the ability for each multipath
      device to have its own queue_mode (whereas before this feature all
      multipath devices effectively had to have the same queue_mode).
      
      This commit also goes a long way to eliminate the awkward (ab)use of
      DM_TYPE_*, the associated filter_md_type() and other relatively fragile
      and difficult to maintain code.
