The hash table consumes entire block. First 64 bytes of the block is fake dirent, whose inode number is 0 (means unused). So when ext2 (or older code which does not know hash index) will use the hash index block for normal dirents, the first fake dirent is replaced as normal entry. So the algorithm still be able to detect the index hash is OK or not, by checking the fake entry still stay FAKE or not, after older code mounts the partition. ..
