Hi Martin,
I think that you would want to ask here:
Paul Menage <menage> {} <google.com>
Li Zefan <lizf> {} <cn.fujitsu.com>
<containers> {} <lists.linux-foundation.org>
These are the maintainers of cgroups within the kernel.
I personally think that this is possible.
However I haven't done any research on that.
Regards,
Marian
