Cool,
thanks for those pointers.
As for the first patch(admittedl I look at another patch
as an example of how it should look.) I googled
a bit, but didn't see much. Then I figured I guess
these guys manually just create these things.
(which isn't the case). All was fine until the
@@ +number -number @@ thread (part)
Which confused me a bit.
But then later on finding info on diff, and now you're pointers
with git(opens a whole new world);
I still need to do more reading up on this, So I can be prepared
in the future if this ever occurs again.

As for the patch itself. If need be I can resend with the signed off
part in the correct location, as well as everybody involved with this.
this way things are legit.
