Now that you mention 2.6 :), I've been trying to update this uxfs
filesystem from an old book[1] for modern kernels:
https://github.com/vvidic/uxfs/
It currently builds and seems to work but it could probably use a
review if someone has a bit of time? I can post the diff here if
that would be easier.

Do you have an actual uxfs filesystem to test against? Having the
mkfs.uxfs and fsck.uxfs utilities would be useful as well.

It is not a filesystem used in real world, but there is mkfs in cmds:
cmds
cmds/fsdb.c
cmds/Makefile
cmds/mkfs.c
kern
kern/Makefile
kern/ux_alloc.c
kern/ux_dir.c
kern/ux_file.c
kern/ux_fs.h
kern/ux_inode.c
LICENSE
Makefile
As for fsck there is only this funny comment :)
kern/ux_inode.c: pr_err("uxfs: %s Filesystem is not clean. Write and run fsck!\n",
