Can I suggest that we don't add new files for additional stats and try
as far as possible to include them in <controller>.stat file. Please
note that we have APIs in libcgroup library which can return
statistics from controllers associated with a cgroup and these APIs
assume that stats are part of <controller>.stat file.
