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.
