I've pulled the patches, but this revert sounds fishy. Is it something
that should have been done together with a commit in a batch introduced
to 4.17? To me, this sounds much like a feature patch, "enable
pre-emption on GVT context" is even written in the tag.

So I'm inclined to drop this patch from -fixes pull.

Is there some specific reason why you don't use Fixes: tagging to
make it easier to track which patches the fixes apply to, if there are
some?
