Thats correct, but I am not sure how the stable folks will pickup these patches.
Thomas, now if we need the patch in any previous  kernels stable tree
(in this instance 2.6.18.x), do we need to backport this patch for
each kernel (which shows this problem)  and send these patches to the
stable tree maintainers or is their some other way  ?
Sorry, but I am not aware of how the stable tree is maintained. Any
information regarding that would be helpful.

Thanks,
Alok
