I guess we can just iterate over all possible zone types from userspace until we find one. Seems a bit hokey, but it would work at least until we add a new zone type and we have to teach the scripts about the new type. But that's a pretty rare event I guess. Let's hope the script writers get this right, and don't make omissions like ZONE_MOVABLE because it's not that common in practice. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
