Add a new fields, VIRTIO_BALLOON_S_BUFFERS and VIRTIO_BALLOON_S_CACHED,
to virtio_balloon memory statistics protocol. The values correspond to
'Buffers' and 'Cached' in /proc/meminfo.
To be able to compute the value of 'Cached' memory it is necessary to
export total_swapcache_pages() to modules.

Add a new fields, VIRTIO_BALLOON_S_BUFFERS and VIRTIO_BALLOON_S_CACHED,
to virtio_balloon memory statistics protocol. The values correspond to
'Buffers' and 'Cached' in /proc/meminfo.
To be able to compute the value of 'Cached' memory it is necessary to
export total_swapcache_pages() to modules.
