Some fixes for VIRTIO_BALLOON_F_FREE_PAGE_HINT. First issue was reported by Alexander Bulekov [1], the other ones were discovered by me when digging into the details.
We keep finding more issues, let's see how we'll proceed with this feature long-term. These patches can be backported to stable QEMU.
