Almost perfect code wise (just the one bug that predates this series I think).

Couple of notes on series from process point of view.

1) Fixes at the front. Makes for uglier series but nicer backporting.
2) Sign-off on everything - even the ones from me that you didn't change. From DCO
   point of view you handled them (passed them back to me ;) so need your
   sign off.  I have occasionally wondered if I should sign off again when this
   happens :)

If you don't do a v2, just reply to say you are fine with me fixing the sign offs
and I can do it whilst applying.

Thanks,

Jonathan
