Actually I wasn't clear in my earlier email. I meant to say "releases
branches", as in 5.19.xxx and not "stable branches". So for 5.19.xxx
we'd pick up these reverts.
And for v6.0-rc if my other patch series [1] fixes the issue, I'd
rather apply [1] than this series. Because this series is meant to be
temporary (I'll be reverting this in the future).
