According to this piece code: " pr_info("Invalid max_ring_order (%d), will use default max: %d.\n", xen_blkif_max_ring_order, XENBUS_MAX_RING_GRANT_ORDER); " if xen_blkif_max_ring_order is bigger that XENBUS_MAX_RING_GRANT_ORDER, need to set xen_blkif_max_ring_order using XENBUS_MAX_RING_GRANT_ORDER, but not 0.
