I'll probably tweak it slightly and drop the "with". So the comment will read:
        /*
         * The guest isn't done hinting, so host sends a notification
         * to the guest to actively stop the hinting.
         */

There is one other spot left which is support for migration. The name
for the VMStateDescription is
"virtio-balloon-device/free-page-report". I am assuming I cannot
rename that. Otherwise all other references to report on the balloon
interface refer to reporting errors from what I can tell.
