Subject[PATCH kernel v8 0/4] Extend virtio-balloon for fast (de)inflating & fast live migration
Date
This patch series implements two optimizations:
1) transfer pages in chuncks between the guest and host;
2) transfer the guest unused pages to the host so that they
can be skipped to migrate in live migration.

Please read each patch commit log for details.

Changes:
v7->v8:
1) Use only one chunk format, instead of two.
2) re-write the virtio-balloon implementation patch.
3) commit changes
4) patch re-org

Liang Li (4):
virtio-balloon: deflate via a page list
virtio-balloon: VIRTIO_BALLOON_F_CHUNK_TRANSFER
mm: add inerface to offer info about unused pages
virtio-balloon: VIRTIO_BALLOON_F_HOST_REQ_VQ
