Michael, any clue on which event we have to wait with
VIRTIO_BALLOON_F_MUST_TELL_HOST? IMHO, I don't think
VIRTIO_BALLOON_F_MUST_TELL_HOST applies to
VIRTIO_BALLOON_F_FREE_PAGE_HINT and we'd better document that. It
introduces complexity with no clear benefit.

I meant that we must wait for host to see the hint.
Why?

Best,
Wei
