I was unsure how to handle this as the previous patches were
individual, I thought perhaps this patch series is a good place to
restart since the work done is a bit different.

I will try to better track what I do in future.

As described before I thought this would hopefully be a good point at
which to reset due to the changes requested by Hans which meant that
the underlying structure is different.

I do have another version already prepped, so I will do my best to
address the previous submissions and your concerns in the cover letter
along with a changelog.
