The newest Linux file-system driver proposed for the kernel is... VMUFAT.
Before getting too worked up about yet-another-Linux-filesystem, VMUFAT is for the vintage Sega Dreamcast game console. The Visual Memory Unit (VMU) on the Dreamcast has a small slab of flash memory formatted with a FAT-based file-system. With the proposed Linux kernel driver in 2026, that file-system on the Dreamcast can be accessed in a hardware-independent manner.
This VMUFAT driver comes just days after another Linux kernel patch surfaced for the Dreamcast. That earlier work was [1]fixes to the GD-ROM driver for the Dreamcast.
The VMUFAT Linux driver comes in at just 1.8k lines of C code. Those interested can find the VMUFAT driver proposal on the [2]Linux kernel mailing list .
