Last march David Miller proposed using kiobuf for these data
transfers, I've written a new patch for 2.4.

(David's original patch contained 2 bugs: it doesn't protect
properly against multiple writers and it causes a BUG() in
pipe_read() when data is stored in both the kiobuf and the normal
buffer)

A couple months ago David posted a revised version of his patch which
fixed both these and some other problems. Most of the fixes were done
by Alexey Kuznetsov.

Later,
