The root cause is I reversed an if statement which caused us to\nset the tb as if there were no owners on the socket if there were, which\nobviously is not correct.\n\nDave I have follow up patches that will add a selftest for this case and I ran\nthe other reuseport related tests as well. These need to go in pretty quickly\nas it breaks kvm, I've marked them for stable. Sorry for the regression,\n\nJosef"}
