Here's a TOTALLY UNTESTED rebase of just that single patch from Dave.

I did not check if the rest of the series did something that this
patch needs, so the patch may be entirely broken, but it does look
sane on its own (ie I do not see anything obviously broken in it). So
it still looks like a nice cleanup, but maybe I'm missing something
subtle, and maybe the rest of Dave's series really is required.

It compiles. That's all I'm going to say about my extensive testing.
Which is also why I haven't added my sign-off to it.

Comments?
