    Which is almost certainly not what you want to happen. Think about direct
    rendering.

    For simple stuff tmpfs already supports size/nr_blocks/nr_inodes mount
    options so you can mount private resource constrained tmpfs objects
    already without kernel changes. No rlimit hacks needed - and rlimit is
    the wrong API anyway.
