Ah-ha, found it. I misremembered the author. :)
https://lore.kernel.org/lkml/20201104235054.5678-1-aarcange@xxxxxxxxxx/

Specifically these two patches:
https://lore.kernel.org/lkml/20201104235054.5678-1-aarcange@xxxxxxxxxx/
https://lore.kernel.org/lkml/20201105001406.13005-2-aarcange@xxxxxxxxxx/


And, Thomas, while I have your attention, I'd really like this to go in
for -rc2, if you can snag it:
