The project (and data structure used) is called KIOBUF.

IIRC Stephen Tweedie and Ben LaHaise are working on it
and it will be a more generic zero-copy IO infrastructure
than io-lite and others.

Ben LaHaise made some documentation (or at least, some
slides) on KIOBUFs for the Ottawa Linux Symposium. You may
be able to get some documentation from him, and you can go
to the OLS ftp site to download an mp3 of the VM lecture...

Also, I'm sure they must have some TODO items for you ;))
(if you're interested in helping out)

regards,

Rik
