Okay. Gen z programmer here. Can you explain this black magic? I see it all the time in kernel code but I have no idea what it means.

I’m struggling with this now. There’s an out of tree module I want upstreamed, but the author (understandably) doesn’t want to put in the work to upstream, so I did. The upstream folks are reluctant to take it because I didn’t actually write it.

I really don’t know what to do.
