Yes, I don't think any subsystem uses these. They dated originally
from when, as part of the initial cgroups framwork, I included a
library that could wrap a mostly-unmodified CKRM resource controller
into a cgroups subsystem, at which point the callback code didn't
necessarily know which subsystem it was being called for. But that's
obsolete now.
