* least 8 bytes, and no more than the remaining space
* left in the directory block.
* - The length of the name in the directory entry (name_len)
- * should be less than (rec_len - 8).
+ * should be less than (rec_len - 8).
* - The inode number in the directory entry should be within
* legal bounds.
* - The inode number should refer to a in-use inode.
