Can't speak for Greg (who I suspect is busy with the merge window to
Linus) but I think this is the right thing to do once the merge window is
over. The unfixed case needs other things to happen first, such as the
removal of tty_lock/tty_unlock. At that point much of this should become
much simpler.
