[PATCH kernel v4 0/7] Extend virtio-balloon for fast (de)inflating & fast live migration
This patch set contains two parts of changes to the virtio-balloon. One is the change for speeding up the inflating & deflating process, the main idea of this optimization is to use bitmap to send the page information to host instead of the PFNs, to reduce the overhead of virtio data transmission, address translation and madvise(). This can help to improve the performance by about 85%.

[PATCH v6 kernel 0/5] Extend virtio-balloon for fast (de)inflating & fast live migration
This patch set contains two parts of changes to the virtio-balloon. One is the change for speeding up the inflating & deflating process, the main idea of this optimization is to use {pfn|length} to present the page information instead of the PFNs, to reduce the overhead of virtio data transmission, address translation and madvise(). This can help to improve the performance by about 85%.

[PATCH kernel v8 0/4] Extend virtio-balloon for fast (de)inflating & fast live migration
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)
