- * Struct leaf_entry's are packed from the top. Names grow from the bottom

- * for the free bytes after the leaf_entry's, but only the N largest such,
- * smaller runs are dropped. When the freemap doesn't show enough space

- * the first-in-the-block key match found, so we should only have to work
- * "forw"ard. If none matches, continue with the "forw"ard leaf nodes
- * until the hash key changes or the filename is found.
