The state of the page in 2024

Funnily, VFAT isn't on my list. That's because VFAT and MSDOS both use the same address_space_operations, so I just counted it as one (FAT).

I think it would make a lovely project for someone to convert the FAT FS from buffer_heads to iomap. That way you'd get large folio support basically for free.

It's probably even a useful thing to do. The storage vendors are threatening us with 16KiB sector sizes and while the block layer should support this nicely, I will have a bit more confidence in the iomap layer. I hope to finish reviewing the bs>PS patches tomorrow.
