Description
The command list hierarchies containing the given subsystem(s) if no subsystem is defined then it displays all mounted hierarchies.
- controller
- defines subsystem whose hierarchy is shown. If this parameter is not used then the command list all mounted subsystems.
- -m, --mount-points
- Display mount points.
- -a, --all
- Display all subsystems (including not mounted ones).

Example
Command lssubsys -am lists all subsystems which are present on the system, mounted ones have attached the mount point:$ lssubsys -am ns cpuset cpu,devices cpuacct /cgroup/cpuacct memory /cgroup/memory freezer /cgroup/freezer net_cls /cgroup/net_cls
Command lssubsys -ami lists all subsystems which are present on the system, mounted subsystems have attached the mount point, not mounted ones which are in some hierarchy have attached the hierarchy number:
$ lssubsys -ami ns cpuset 5 cpu,devices 6 cpuacct /cgroup/cpuacct memory /cgroup/memory freezer /cgroup/freezer net_cls /cgroup/net_cls
