           Summary: e2fsck -fD on ext4 breaks
           Product: File System
           Version: 2.5
    Kernel Version: 2.6.32.10
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: ext4
        AssignedTo: fs_ext4@...nel-bugs.osdl.org
        ReportedBy: khcha.n.el@...il.com
        Regression: No

i did a e2fsck -fD on a ext4 filesystem, later a e2fsck -f complains a bunch of
errors. if i e2fsck -fy would end up a bunch of files go into lost+found or
simply lose trace.

Step to reproduce:
1. prepare a ext4 file system (dd if=/dev/zero of=test_ext4.img bs=1M
count=1000 && mkfs.ext4 test_ext4.img)
2. mount it (mount -t ext4 -o rw,loop test_ext4.img /mnt/tmp)
3. put some files on it, it seems to me that tiny files would cause the issue
(cp -r /home/$USER/.gconf /mnt/tmp)
4. un mount it (umount /mnt/tmp)
5. e2fsck -f test_ext4.img  all good
6. e2fsck -fD test_ext4.img seems fine
7. e2fsck -f test_ext4.img here comes trouble...

Components version:
Distro: Archlinux
Architecture: x86_64

kernel 2.6.32.10
e2fsck 1.41.10 (10-Feb-2009)
    Using EXT2FS Library version 1.41.10, 10-Feb-2009
