How different? You found some old code and use it as argument that you
can do the same:

"Here I just followed the approach taken by Adreno GPU bindings for the"

You explain what you did, but you did not explain why or how I mixed
anything.

I did not say you had discussions before. I said exactly same problems
were being solved and I give here and there exactly the same feedback.
