pagecache for pages above lower limit but that is a separate question about driver design, I would like to make sure I understand the high level design first. > > > > Note that users could not care less about how a driver > > is implemented internally. > > > > Is there some workload where you see VM working better with > > this than regular balloon?

This patchset follows the main idea discussed at 2012 LSFMMS section: "Ballooning for transparent huge pages" -- http://lwn.net/Articles/490114/ to introduce the required changes to the virtio_balloon driver, as well as changes to the core compaction & migration bits, in order to allow memory balloon pages become movable within a guest. Rafael Aquini (4): mm: introduce compaction

Memory fragmentation introduced by ballooning might reduce significantly the number of 2MB contiguous memory blocks that can be used within a guest, thus imposing performance penalties associated with the reduced number of transparent huge pages that could be used by the guest workload.

This patchset is for kernel and contains two parts of change 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
