Right - this is the first of the "Open Issues" that I mentioned in the patch. The question is how to display the multiply-bindable subsystems in /proc/cgroup in a way that won't break backward-compatibility. Options include: - always display one line for each subsystem; if a subsystem is multiply-bindable then the "hierarchy id" and "num cgroups" columns may be empty or have multiple (comma or slash-separated?) values - for a multiply-bindable subsystem, have a header line to indicate that the subsystem exists, and then a separate line for each bound instance of the subsystem. Either of these could confuse existing userspace parsers, but I'm not sure that any exist other than libcgroup, and I don't think it's in wide use yet.
