To replicate the bug, create two filesystems, one with `mkfs.ext4 -I 256`, one with `mkfs.ext4 -I 256 -O inline_data`. An inode size of 256 bytes is the default, but included here for clarity. To do this, you are going to need an `e2fsprogs` from trunk, or version 1.43 if it has been released.

Mount the two filesystems, in each of them do:
    $ ln -s $(for i in {1..64}; do echo -n .; done) 64
    $ ln -s $(for i in {1..128}; do echo -n .; done) 128
    $ ln -s $(for i in {1..192}; do echo -n .; done) 192
    $ ls -l 64 128 192

Both directory listing will show symlinks named `64`, `128` and `256`, each pointing to a filename with the corresponding amount of dots. This is the expected behavior.

Unmount both filesystems, mount them again. Do the `ls -l` again.

The default filesystem will show the same output as previously, the one with inline_data activated will show the `128` symlink pointing to a filename of only 64 dots.
