      block: drop custom queue draining used by scsi_transport_{iscsi|fc} · 86072d81
      Tejun Heo authored
      iscsi_remove_host() uses bsg_remove_queue() which implements custom
      queue draining.  fc_bsg_remove() open-codes mostly identical logic.
      
      The draining logic isn't correct in that blk_stop_queue() doesn't
      prevent new requests from being queued - it just stops processing, so
      nothing prevents new requests to be queued after the logic determines
      that the queue is drained.
      
      blk_cleanup_queue() now implements proper queue draining and these
      custom draining logics aren't necessary.  Drop them and use
      bsg_unregister_queue() + blk_cleanup_queue() instead.

      block: add bsg helper library · aa387cc8
      Mike Christie authored
      This moves the FC classes bsg code to the block layer and
      makes it a lib so that other classes like iscsi and SAS can use it.
      
      It is helpful because working with the request queue, bios,
      creating scatterlists, etc are a pain that the LLD does not
      have to worry about with normal IOs and should not have to
      worry about for bsg requests.
