maybe good. *but* active/incative ratio in lru file cache is good estimation for this.

This is the point. At last. Why "# of shared pages" is important ?

I wonder it's better to add new stat file as memory.cacheinfo which helps
following kind of commands.

  #cacheinfo /cgroups/memory/group01/
       /usr/lib/libc.so.1     30pages
       /var/log/messages      1 pages
       /tmp/xxxxxx            20 pages
       .....
       .....

Thanks,
