I'm the author of the post. Unfortunately, I cannot link to the original patch I sent (it was very different) because I only sent it to the Linux kernel security mailing list. I wish I had saved it somewhere so I could show it.
On a related note Christophe Leroy should be applauded for his calm and matter of fact response. I don’t know if I would be capable of that.
(Totally with you though: maintainer was a douche. People are the worst.)
