Hello, Linus.
These are changes to implement namespace support for cgroup which has
been pending for quite some time now. It is very straight-forward and
only affects what part of cgroup hierarchies are visible. After
unsharing, mounting a cgroup fs will be scoped to the cgroups the task
belonged to at the time of unsharing and the cgroup paths exposed to
userland would be adjusted accordingly.
The branch is forked off of cgroup/for-4.6, so it'd be best to pull
cgroup/for-4.6 before this branch.
Thanks.
