Yeah, that is in Andrew's "post linux-next" patch series, so if you
rebase it on top of linux-next and then send it to Andrew with some
explanation.

Actually, if it is intended for the stable trees, then presumably it is
intended to go to Linus for the current release?  In which case, the
patch in Andrew's tree will have to be changed to cope after your patch
appears in Linus' tree (and therefore, linux-next).
