Hi Mike, 

I have created a personal branch [1] with remaining patches with the small
fixes I pointed on the review.  It just to make it simpler you give me ack
and avoid resending all the patch all over again.

Florian, I am using the original naming scheme as indicated above. I think
we should follow what is expected from standard once we have an actual 
implementation.
