This patch-set adds support for the new feature 'deflate-on-oom'
that has been added to the QEMU virtio memory balloon a month ago.
This feature lets a guest OS deflate balloon on OOM.

With 'deflate-on-oom' enabled virtio balloon will release
it's memory if possible right before an OOM termination of
processes.

QEMU commit with the complete feature description:
