Subject: [PATCH][RFC] network splice receive v3

Hi,

Here's an updated implementation of tcp network splice receive support.
It actually works for me now, no data corruption seen.

For the original announcement and how to test it, see:

http://marc.info/?l=linux-netdev&m=118103093400770&w=2

The splice core changes needed to support this are now merged in
2.6.22-git, so the patchset shrinks to just two patches - one for adding
a release hook, and one for the networking changes.

The code is also available in the splice-net branch here:

git://git.kernel.dk/data/git/linux-2.6-block.git splice-net

There's a third experimental patch in there that allows vmsplice
directly to user memory, that still needs some work though.

Comments, testing welcome!
