Thanks, this looks correct indeed. If we are using persistent grants the
indirect_pages list should always be empty because blkfront has
pre-allocated enough persistent pages to fill all requests on the ring.

Acked-by: Roger Pau Monné <roger.pau@xxxxxxxxxx>

Should be backported to stable branches.

Roger.
