    Here's my super-complex patch btw, to achieve exactly the same thing
    from userspace without involving any kernel or systemd patching and
    kernel-side logic. Simply edit your own ~/.bashrc and add this to the end:

    if [ "$PS1" ] ; then
    mkdir -m 0700 /sys/fs/cgroup/cpu/user/$$
    echo $$ > /sys/fs/cgroup/cpu/user/$$/tasks
    fi

    Then, as the superuser do this:

    mount -t cgroup cgroup /sys/fs/cgroup/cpu -o cpu
    mkdir -m 0777 /sys/fs/cgroup/cpu/user

    Done. Same effect. However: not crazy.

    I am not sure I myself will find the time to prep some 'numbers' for
    you. They'd be the same as with the kernel patch anyway. But I am sure
    somebody else will do it for you...
