Subject: [BUG][e2fsprogs] e2fsck: e2fsck reports ext3 message when checking
 ext4 filesystem

Hi,

I use "e2fsck" to repair the damaged ext4 device.

The message was followings.

------
# ./e2fsck /dev/sdb3
e2fsck 1.41.3 (12-Oct-2008)
Superblock has an invalid ext3 journal (inode 8).
Clear<y>?
---

Why e2fsck tells me "ext3"? It looks the message was wrong
or e2fsck doesn't recognize ext4 correctly.

Thanks！
Miao Xie
