      xen/blkback: Move the plugging/unplugging to a higher level. · 97961ef4
      Konrad Rzeszutek Wilk authored
      We used to the plug/unplug on the submit_bio. But that means
      if within a stream of WRITE, WRITE, WRITE,...,WRITE we have
      one READ, it could stall the pipeline (as the 'submio_bio'
      could trigger the unplug_fnc to be called and stall/sync
      when doing the READ). Instead we want to move the unplugging
      when the whole (or as a much as possible) ring buffer has been
      processed. This also eliminates us doing plug/unplug for
      each request.
