-m, --mount-points: Display mount points. Only the first mount points of shown hierarchies are displayed.
-M, --all-mount-points: Display mount points. All mount points of shown hierarchies are displayed, each on separate line.
-a, --all: Display all subsystems (including unmounted ones).
-i, --hierarchies: Display the attached hierarchy number if the subsystem is in a hierarchy. If the option -m is also used, the hierarchy number is shown only for unmounted hierarchies.
-h, --help: Display help and exit.

EXAMPLE

The command lssubsys -am lists all subsystems which are present in the system, mounted ones will be shown with their mount point:

$ lssubsys -am
ns
cpuset
cpu,devices
cpuacct /cgroup/cpuacct
memory /cgroup/memory
freezer /cgroup/freezer
net_cls /cgroup/net_cls

The command lssubsys -ami lists all subsystems which are present in the system, mounted subsystems are listed with their mount points, unmounted ones which are in a hierarchy are listed with their hierarchy number:

$ lssubsys -ami
ns
cpuset 5
cpu,devices 6
cpuacct /cgroup/cpuacct
memory /cgroup/memory
freezer /cgroup/freezer
net_cls /cgroup/net_cls
