That's my only worry.

I'd suggest we queue this but not send it to Linus now. Instead, let it
cook in linux-next for the whole 6.5 release cycle so that it can get at
least *some* testing.

Because if we send it now and something else obscure breaks in a weird
way in his tree, then we'll have to scramble to fix that too and it'll
be one helluva mess.
