    The general idea of limiting total socket buffer memory consumed by a
    cgroup is a fine idea, but I think it needs to be integrated more
    closely with the existing kernel memory cgroup tracking efforts,
    especially if you're trying to use as generic a name as "kmem" for it.

    I agree with Kamezawa's comments that you need a lot more documentation.
