Understood, and I cannot show such an advantage. struct idr is already
built on the same underlying tree as the xarray, so there is nothing
measurable to gain here in speed or memory -- it would be churn for its
own sake. I will drop the conversion.

Thank you for answering so quickly, and for explaining the reasoning
rather than just saying no. That was useful to me.

If there is something in fastrpc, or elsewhere in drivers/misc, that you
would actually like to see worked on, I would be glad to take on
something small and learn from the review.

Thanks,
