- * A directory entry has a struct direct at the front of it,
- * containing its inode number, the length of the entry, and the
- * length of the name contained in the entry.  These are followed
- * by the name padded to a 4 byte boundary with null bytes.  All
- * names are guaranteed null terminated.  The maximum length of a
- * name in a directory is MAXNAMLEN.
+ * The kernel defines the format of directory entries returned by 
+ * the getdirentries(2) system call.
