I'm just not sure how it would turn out. I guess it would be an
overall win under loaded situations due to lowered cache footprint but
I don't think it will be anything which would stand out.

Sure, fair enough but there's also a different side. It'll allow much
easier implementation of things like in-kernel media presence polling
(I have some code for this but it's still just forming) and
per-device. It gives a much easier tool to extract concurrency and
thus opens up new possibilities.

So, anyways, alright, I'll go try some conversions.

Happy holidays.
