示例1: areHostCgroupsMounted

func areHostCgroupsMounted(enabledCgroups map[int][]string) bool {
	controllers := cgroup.GetControllerDirs(enabledCgroups)
	for _, c := range controllers {
		if !cgroup.IsControllerMounted(c) {
			return false
		}
	}

	return true
}

示例2: mountHostCgroups

// mountHostCgroups mounts the host cgroup hierarchy as required by
// systemd-nspawn. We need this because some distributions don't have the
// "name=systemd" cgroup or don't mount the cgroup controllers in
// "/sys/fs/cgroup", and systemd-nspawn needs this. Since this is mounted
// inside the rkt mount namespace, it doesn't affect the host.
func mountHostCgroups(enabledCgroups map[int][]string) error {
	systemdControllerPath := "/sys/fs/cgroup/systemd"
	if !areHostCgroupsMounted(enabledCgroups) {
		if err := cgroup.CreateCgroups("/", enabledCgroups); err != nil {
			return fmt.Errorf("error creating host cgroups: %v\n", err)
		}
	}

	if !cgroup.IsControllerMounted("systemd") {
		if err := os.MkdirAll(systemdControllerPath, 0700); err != nil {
			return err
		}
		if err := syscall.Mount("cgroup", systemdControllerPath, "cgroup", 0, "none,name=systemd"); err != nil {
			return fmt.Errorf("error mounting name=systemd hierarchy on %q: %v", systemdControllerPath, err)
		}
	}

	return nil
