- * encoded in the "extent + ext_attr_length" fields of _all_ the
- * redundant entries for the directory.  Thus, it can always be
- * reached regardless of which directory entry you have in hand.
- *
- * This works because the "." entry is simply the first directory
- * record when you start reading the file that holds all the directory
- * records, and this file starts at "extent + ext_attr_length" blocks.
- * Because the "." entry is always the first entry listed in the
- * directories file, the normalized "offset" value is always 0.
- *
- * You should pass the directory entry in "de".  On return, "block"
