For the reference, previous discussion of the problem: https://lore.kernel.org/kvm/87zgg6sza8.fsf@xxxxxxxxxx/ The patch to fix this: https://lore.kernel.org/kvm/20221004123956.188909-19-vkuznets@xxxxxxxxxx/ is part of "KVM: x86: hyper-v: Fine-grained TLB flush + L2 TLB flush features" series (v11: https://lore.kernel.org/kvm/20221004123956.188909-1-vkuznets@xxxxxxxxxx/) which I hope to see in 6.2 (fingers crossed!), however, it is unlikely to go to stable@ unless we know that there's a real problem to fix. I'll backport it then. -- Vitaly
