It hasn't made it upstream yet (I > hope!). That was actually just merged this morning into Linus' tree. I'm still happy to take the fix via my tree, but you're welcome to take it via a BPF tree as well. I'm juggling some other patches right now, just LMK what works on your end. IMO it should have a fixes tag: it's a bit of a grey area, but one something's in I generally try and put those tags on it. That way folks who try and backport features at least have a shot at finding the fix (or at least, finding the fix without chasing around the bug ;)). I also tried poking you guys on the BPF Slack, but I don't really use it and I'm not sure if anyone else does either.
