Can somebody explain this? du & ls showing different sizes

[Vijay Gill]

Back again with another observation.

I found out that this issue happens only with
kernel-2.6.27.12-170.2.5.fc10.i686 (the latest one I have). I had a
previous kernel too (kernel-2.6.27.9-159.fc10.i686) and there is no
problem with that. I tried compare the change log of the two rpms and
there seemed nothing about changes to XFS.
