The first two patches (generic_sendpage.patch and sendfile.patch)
should be all you need. But they were rather quick hack and I haven't
seriously looked at them for quite a while.

Maybe I should change that. Several people appear to be generally
interested in the subject.


Data dominates. If you've chosen the right data structures and organized
things well, the algorithms will almost always be self-evident. Data
structures, not algorithms, are central to programming.
