Yeah I put the changelog in the cover letter.  There were no changes on
this patch, though I admit that wasn't entirely clear now re-reading the
cover letter text.  I also didn't account for the fact that you probably
aren't reading the whole series since I only Cc'd you on this patch, not
the whole series.  In any case, I probably shouldn't have re-sent the
whole series after one minor modification to one patch in the series.
