There doesn't seem to be anything particularly xen specific about your
patch. I think you will likely find more people able to help on the
netfilter lists (see the MAINTAINERS file).
However I'd first recommend reading Documentation/CodingStyle and
Documentation/SubmittingPatches as well as rebasing to a much newer
kernel than 2.6.18 (which is ancient even by Xen standards). You might
find ./scripts/checkpatch.pl useful as a rough guide to the coding style
fixes.
