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.
