SubjectRe: RFC [PATCH v4 2/7] Enable balloon drivers to report inflated memory

I'm confused, I think we care about actual adjustment of the total pages
available here, that we want to notify the system about. These
approaches (vmware, virtio-balloon with deflate-on-oom) don't adjust
totalpages, because the assumption is that we can get back the inflated
memory any time we really need it automatically.
