This series is puzzling:

    - The subject of this email says there are 9 patches.

    - The summary above says that there are 8 patches.

    - The subjects of the followups to this email say that there are 14
      patches, but only patches 7 through 14 are in patchwork or the
      archive.

Please explain!

Thanks,

Ben.
