That's still not quite useful tbh, lemme bring the diff stat I wrote
in previous email just in case you missed it:

These diff stats were taken by removing "exfat_" prefix from the
current staging drivers.

But if that's still what you want, I'll do it.
btw, removing "exfat_" prefix from the current one makes more sense imo.

If we add "exfat_" prefix to the new one, we get weird file names like
"exfat_core_exfat.c".

Well, I think you got me confused with Namjae.
(Yeah Korean names are confusing I know :) )

Namjae (or anyone else from Samsung) should answer that, not me.

I just prepared a patch as we were getting nowhere like you mentioned :)

Sorry.
I'll add that back for v2.

The sdFAT code release explicitly states "either version 2 of the
License, or (at your option) any later version", so I thought that
makes sense:
https://github.com/arter97/exfat-linux/commit/d5393c4cbe0e5b50231aacd33d9b5b0ddf46a005

Please correct me if I'm wrong.

Thanks.
