If I'm reading https://lore.kernel.org/r/CAL_JsqKZ6cEny_xD8LUMQUR6AQ0q7JKZMmdP-9MUZxzzNxZ3JQ@mail.gmail.com/ correctly - the warnings are expected but there needs to be a change to properties, so CR? (FWIW I'd lean towards allowing it still, even tho net-next got closed. Assuming v2 can get posted and acked today.)
