Both nr_descendants and max_descendant_depth can be found easily from
userspace by scanning the cgroup directory. nr_dying_descendants is a
transient figure and it should be 0 most of the time. So I wonder how
useful it can be.

This new interface file will be more useful if it can reveal information
that cannot be easily obtained by looking from userspace alone.
