The rename of that variable is just cosmetic, true, but I'd still be
inclined to back-patch it.  If we don't do so then I'm afraid that
future back-patched fixes might be bitten by the same confusion,
possibly introducing new real bugs.

Having said that, keeping the two aspects in separate patches might
ease review and testing.

I think it's about 50/50, TBH.  I'd stick with whichever style is
being used in nearby code.
