Thanks Balbir- I thought that should work, but I was getting thrown by another issue entirely. Once I have a cgroup struct from cgroup_get_cgroup(), it would be helpful to know what controllers it contains. I can get a cgroup_controller struct with cgroup_get_controller(), but I need to know the controller name is to get that. Is there a method to return the list of controller names (or controller structs) that are in a cgroup?
