I am fine with doing either, what ever Linus finds works best for
him. The only reason I went to the direct pull request for apparmor
was that as I as understood it Linus wanted the larger LSM pull
requests separated out so that it was easier for him to see what was
in them.

And again sorry, I screwed up, it should not have happened, my
perspective was incorrect and I know I need to make it right.
