It's really not that hard, using git, to refactor a patch. If it's such
a mess that you can't refactor it then it's probably a good indication
that said patch should not be merged. The vast majority of other
maintainers in the kernel would never accept such a large convoluted
patch as it's too difficult to determine if something unintended changed
and it makes debugging and bisecting (once it's merged) more difficult.
Not to mention the fact that few developers are willing to put in the
time to untangle it enough to properly review.

I agree with Allen. The unions are completely unnecessary. If there was
a space constraint then they could be justified but we really don't have
that here. In my opinion, you should just drop them -- a comment doesn't
really improve things much.
