In case the general impression wasn't clear from the earlier comments.
This patch is an interesting benchmark tweak, but unlikely to ever
make it into the mainline kernel. The kernel needs to be a general
purpose system and deal with multiple types of hardware and resource
control.

But don't give up looking at performance. If you can find ways to
speed up the overall socket buffer handling without breaking existing
semantics; then the patches would be positively received.
