what security fix?

are you suggesting that kernel developers send patches on paper and integrators retype them carefully avoiding the security impact related info? impressive assumption, to say the least. because if that's not how kernel development works than your example has nothing to do with this thread's topic. as a sidenote, if you have to retype something then you don't 'have' it. you would 'have' it if you could copy-paste or attach it. incidentally, that's much more like how patches flow in kernel development. so give this one another try ;).
