How about we provide a interface to make you able to specify which pages
should be charged to which cgroup, then you may create two cgroups for the
two files, set each of them to the desired size which you want the cache of
the file to be. By that way you can control them as exactly as you want.
The current memcg allows a group which has not any processes but still
pages in soft limit tree (hope I'm not wrong) so you dont' have to put any
of you worker process into the groups either.
