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. Paul -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
