[PATCH][RFC] network splice receive v3

[Jens Axboe]

 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!
