Thanks everyone involved in this contribution. I appreciate the effort 
of showing that such new API is really needed and will be used by other 
subsystems. I see benefits from this approach and I hope that any 
pending issues can be resolved incrementally.

I've applied this patchset to dma-mapping-next branch and it will be 
also available as dma-mapping-for-6.16-two-step-api [1] stable branch 
for those who wants to base their pending work on it.
