If you've got the actual owner you can do full blown PI, which is tons better than a 'do-something-random' call. The only reason the whole non-virt pause loop filtering muck uses it is because it really doesn't know anything, and do-something is pretty much all it can do. Its a broken interface. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
