dirn is no use in UFS file system?

Hi, pals!

I take a look at Programming Guide and find that when locating a
cached object on disk, UFS system only use filen, L1 and L2 to locate
the object on disk.

IMHO, dirn has no use when locating the cached object on disk when
the file system is UFS. Am I correct?

What is the use of dirn when the file system is UFS? Only used to
find cache_dir? I think so. Am I correct at this point?

Best regards,
George Ma
