I think it is good to separate these patches. Dan (copied here) wrote the
code for the
Xen self balloon driver. If it is ok with him I can submit the patch for
Xen as well.

It may be useful to be able to access vm_committed_as from device

the available physical memory amongst all competing virtual machines
hosted on a given node. This policy engine is driven by a number of metrics
including the
