Quoting Daniel Lezcano (daniel.lezcano at free.fr):
> This patch is sent as an answer to a previous thread around the ns_cgroup.
> It adds a control file 'clone_children' for a cgroup.
> This control file is a boolean specifying if the child cgroup should
> be a clone of the parent cgroup or not. The default value is 'false'.
> This flag makes the child cgroup to call the post_clone callback of all
> the subsystem, if it is available.
> At present, the cpuset is the only one which had implemented the post_clone
> The option can be set at mount time by specifying the 'clone_children' mount

Paul and Eric, do you have any objections to this set? Patch 2 in
particular will make it easier to use both libvirt-lxc and lxc.sf.net
containers at the same time, without having to reboot.
