32 | * General rules: | |
33 | * | |
34 | * We accept named hierarchies in the syntax "foo" and "name=foo". | |
35 | * | |
36 | * We expect that named hierarchies do not conflict in name with a | |
37 | * kernel hierarchy, modulo the "name=" prefix. | |
38 | * | |
39 | * We always generate "normalized" controller names, i.e. without the | |
40 | * "name=" prefix. | |
41 | * | |
42 | * We require absolute cgroup paths. When returning, we will always | |
43 | * generate paths with multiple adjacent / removed. | |
