The hard part - getting Microsoft to OK merging an exfat driver - is done.

All we need now is to get a driver cleaned up. :)

I'm working off a somewhat cleaned up copy of Samsung's original driver,
because that's what I had knowledge of.  If the sdfat driver is closer to being
mergeable, I'd not object if that got merged instead.

But here's the problem... Samsung has their internal sdfat code, Park Yu Hyung
has what appears to be a fork of that code from some point (and it's unclear ,
and it's unclear which one has had more bugfixes and cleanups to get it to
somewhere near mainline mergeable.

Can you provide a pointer to what Samsung is *currently* using? We probably
need to stop and actually look at the code bases and see what's in the best
shape currently.
