I didn't get the first message in this thread, so I'm not sure I
completely understand the context of the question, but it's correct
that the signed vs. unsigned char problem with the hash algorithm only
applies to ext3 and ext4 filesystems, since ext2 doesn't have support
for htree directory indexing, which is where the issue showed up.

As far as I know there are no current signed vs unsigned issues in
ext2/3/4, assuming you are using modern kernels and e2fsprogs.
