[suggestion] FullFAT library adoption
Dunno if can help, BTW ReactOS devs apreciated (and adopted) it:
FullFAT is a fully featured FAT 12/16/32 library. It features optional LFN (Long File-name support)
I have begun writing this library because I am dissatisfied with the many Free FAT implementations, the ones that implement LFN’s are bloated and slow, like the FreeDOS driver. Others are lacking in features, buggy, or no longer actively developed.
The aim is make a really high-quality FAT driver that is flexible for many different needs, and do it better than any commercially available option.

It always depends how easy it is to port the driver, and how good the native FS driver is as well ;)

Interesting, but the FullFAT's licence (GPL) is not compatible with the Haiku' licence (MIT)
