[PATCH kernel v5 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 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%.
