    There is a test tool that you can download there:

    https://tglx.de/~fweisbec/task_counter_test.tar.gz

    It tests various things to ensure the subsystem behaves
    as expected:

    - correct tasks.usage value when tasks are moved around
    - correct fork and cgroup migration rejects if limit
    is reached
    - correct propagation of limit to parents
    - correct protection against forkbombs
    - test killing of tasks in a cgroup
    - ...
