Hello! I will be rebasing -rcu onto v5.12-rc2. On the other hand, I well recall when running rcutorture on -rc1 was foolhardy, so actually a sign of progress [1]. And no, rcutorture does not use swap, so I have been blissfully ignorant. My fervent apologies to anyone who attempted to run -rcu on a configuration requiring swap! Thanx, Paul [1] https://lwn.net/Articles/848431/
