Add NR_BALLOON_PAGES counter to track memory used by balloon drivers and
expose it through /proc/meminfo and other memory reporting interfaces.
In balloon_page_enqueue_one(), we perform a
__count_vm_event(BALLOON_INFLATE)
and in balloon_page_list_dequeue
__count_vm_event(BALLOON_DEFLATE);
Should we maybe simply do the per-node accounting similarly there?
BTW should virtio mem be tied into this too, in some way? or is it too
different?
No, we should limit it to actual balloon drivers that e.g., never
completely remove memory.
