There's still tons of duplication. There should be no code in the
filesystem except for a few callouts for the inode init and chmod path,
and the attr set/get should also be mostly in a library. If you need
to add more than 20 lines to the filesystem you did something wrong.

One acl structure implementing the Posix and NFSv4 acls and instead
of a big pile of duplicate infrastructure.
