That would work.

It's usually very obvious, because the first patch is `origin.patch'
(Linus's latest tree against his most-recent-release) and there's no way in
which that patch will apply to the wrong tree.

It just happened that the particular series you grabbed had an empty
origin.patch.

umm, OK, I'll put a file in there called stamp-yyyy-mm-dd-hh-mm

I warned you ;)

Yup, thanks, I refreshed it.
