This is not a RESEND.  These things very much matter because I'm sitting here
trying to figure out whether I need to review this "v2", which is really v3, or
whether I can just review the real v2.

  Don't add "RESEND" when you are submitting a modified version of your
  patch or patch series - "RESEND" only applies to resubmission of a
  patch or patch series which have not been modified in any way from the
  previous submission.
