Uh. You're confused :-)
UFS is the Unix file system, defining the inode, directory, etc.
formats. FFS, the fast file system, is a back-end for UFS providing
the block allocation stuff, etc.
In now-ancient BSD releases, it was all just called "UFS", but in
4.4BSD, they split things up a bit. This allows LFS, which is basically
UFS with different block allocaiton policies, etc. to share a bunch
of the same code.
