As said previously, I don't see why this needs to have a separate
#define at all - it's simply __RING_SIZE(). No adding this would
also imply that - apart from perhaps documenting the new xenstore
nodes - io/blkif.h would need changing at all (which otherwise would
require a hypervisor side patch to be submitted too).
