IMHO there is a right and wrong, at the very least inside a computer.
If we can't read the documentation (Documentation/memory-barriers.txt)
and decide if the patch is correct or incorrect (I'm not saying I can
with 100% certainty) then perhaps we should ask somebody who can?

BTW, I also hate code that is there just because somebody has a fuzzy
feeling it helps. We definitely don't need more of that. But I do like
code that is correct in principle, code that I can change and get a
predictable result. Code that works most of the time on most platforms
(as long as I don't make any changes) is no friend of mine.
