OS: Linux 2.6.0-test9
FS: ext3
Maybe this is since I added the dir_index feature to ext3, but I'm not
sure.

As you can see it involves the whole filesystem.
I created a new ext3 filesystem. Without the dir_index feature I get the
order as you expect. But with the dir_index feature I get a skewed order.
So I would say this is a result of the dir_index feature of ext3.
J�rg.
