[PATCH v20 4/7] virtio-balloon: VIRTIO_BALLOON_F_SG
...s step 2) by transferring pages to host in sgs. An sg
describes a chunk of guest physically continuous pages. With this
mechanism, step 4) can also be optimized by doing address translation and
madvise() in chunks rather than page by page.
With this new feature, the above ballooning process takes ~460ms resulting
in an improvement of ~89%.
TODO:
- optimize stage 1) by allocating/freeing a chunk of pages instead of a
single page each time.
- sort the internal balloon page queue.
