Yeah, I saw the do_sendfile one and decided we don't care. Not only is
is out of POSIX spec (so if you break it you get to keep both pieces),
the whole sendfile() thing is a bit of a hack.
But we could take the f_pos_lock explicitly in do_sendfile for the
!ppos case if we decide we care. The error handling is the main
annoyance.
