Plus, Linus has been heard to say that he now believes sendfile() to have been a mistake. This doesn't mean it will go away of course (it's a syscall, it's immortal) but if sendfile() can be implemented in terms of splice(), so much the better!

Ah, now I looked at the Linux manpage of sendfile and I understand a bit
better. BSD sendfile is _much_ more convenient; it is zero copy, the
special case of count = 0 means "all the data there is", and it has
additional argument that makes it possible to string multiple buffers
a la sendmsg. I have assumed the Linux one was a clone, while in fact
the splice proposal looks more like BSD sendfile.
