+ * General rules:
+ *
+ * We accept named hierarchies in the syntax "foo" and "name=foo".
+ *
+ * We expect that named hierarchies do not conflict in name with a
+ * kernel hierarchy, modulo the "name=" prefix.
+ *
+ * We always generate "normalized" controller names, i.e. without the
+ * "name=" prefix.
+ *
+ * We require absolute cgroup paths. When returning, we will always
+ * generate paths with multiple adjacent / removed.
