This patchset adds namespace-like feature to the existing cgroup system.
When used with a container system (eg. lxc) it allows containers to have
its own cgroup hierarchy, enabling use of 'systemd' (using cgroups) inside
a container.
The behaviour is not changed at all when isolation_root flag is not set,
no additional overhead is added.
I'm really not sure if the 'mount' part (patch 5) is done correctly, please
review carefully.
Witold Krecicki (6):
cgroup: add cgroup.isolation_root flag entry to the cgroup filesystem
cgroup: make 'cgroup_is_descendant' function take cgroup as a
'descendant of' argument
cgroup: add 'root' parameter to cgroup_path function
cgroup: disallow task from leaving cgroup isolated root
cgroup: make cgroup filesystem mounts performed by task inside
isolation root see its isolation root as top cgroup
cgroup: documentation of isolation_root cgroup flag
