A task group is a set of percpu runqueues. The root task group is the
top level set in a hierarchy of such sets when group scheduling is
enabled, or the only set when group scheduling is not enabled. The
autogroup hierarchy has a depth of one, ie all autogroups are peers
who's common parent is the root task group.
