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.
