Note since Torvald's mastter branch still does not have a fix for this,
Greg has gone with a straight forward revert for all the stable series
including 5.1.x .
This means that the rawhide kernels are currently still broken, I
suggest that we pick-up Greg's revert and add that as a downstream patch
to the rawhide kernels for now.
Greg's patch has not been pushed to the linux-stable repo yet,
so I will forward it to kernel(a)lists.fedoraproject.org.
Thanks for the reminder, I've added the patch to Rawhide so it should be
in the next build. I included the revert in v5.1.9 (in updates-testing)
