+  cpuset.sched.domain_root

Why are we calling this a domain_root and not a partition?

A partition can consist of several cgroups in a tree structure. That
flag should only be set at the root of a partition. I will change the
name to partition_root if you think this name is acceptable.

The flag indicates the 'effective_cpus' things of the current group is a
partition. The fact that it can have sub-partitions doesn't really
matter does it.

Just call it 'partition', leave out the whole root stuff, all of cgroup
is hierarchical and you can have sub-groups we don't go around calling
everything a root.
