Oh, interesting, OK. I guess then given that it's not super important
and how late we're in the game, I'll just throw it into the (relatively
small) pile we have for UML for -next. Given that we removed the pcap
driver in 6.11 (12b8e7e69aa7a) I guess we could even ask stable to take
it, but it's not even that important until someone wants to test the
rust DRM stuff in kunit or something :)
