Ritesh, Adrian,

I realized that Adrian requested a minor fixup of patch6. However to
simplify a bit for all of us, avoiding another new version of the
series being sent I decided to pick this series as is.

Adrian, I even took the liberty of adding your ack for patch6. I also
trust Ritesh to make a fix for patch6, but on top of the series I have
just applied.

If you have any objections, please tell me!

Kind regards
Uffe
