Well, cgrp->name is a pointer to struct cgroup_name.

At first I tried to declare cgrp->name as char *, and use container_of()
to get struct cgroup_name, but it didn't result in simpler code.

Hmmm?  But then what prevents defining const struct cgroup_name?

static const struct cgroup_name root_cgroup_name = { .name = "/" };

Can't... That's char name[0] not char *name.

I'll allocate a global struct cgroup_name *root_cgroup_name, and use it
for all root_cgroup->name and dummytop->name.
