Yes. Lets start with it - no separate groupings for a while. BTW I think that hierarchy is a good (and easier to make than) replacement for separate grouping. Say if I want two groups to have separate CPU shares and common kmemsize this is the same as if I want one group for kmemsize with two kids - one for X% of CPU share and the other for Y%. And this (hierarchy) provides more flexibility than "plain" although separate grouping. Moreover configfs can provide a clean interface for it. E.g. $ mkdir /configfs/beancounters/0 $ mkdir /configfs/beancounters/0/1 $ mkdir /confgifs/beancounters/0/2 and each task_struct will have a single pointer - current container - but not 10 - for each controller.

I agree with Paul Menage that having /configfs/beancounters/<id>/tasks and /.../threads is perfect. ------------------------------------------------------------------------- Using Tomcat but need to do more?
