Ah-ha, found it. I misremembered the author. :)
https://lore.kernel.org/lkml/20201104235054.5678-1-aarcange@redhat.com/
Specifically these two patches:
https://lore.kernel.org/lkml/20201104235054.5678-1-aarcange@redhat.com/
https://lore.kernel.org/lkml/20201105001406.13005-2-aarcange@redhat.com/
And, Thomas, while I have your attention, I'd really like this to go in
for -rc2, if you can snag it:

:)
Thanks!
