Subject: [PATCH 1/5] KVM: nSVM: fix a typo in svm_leave_nested
Date: Mon,  3 May 2021 15:54:42 +0300	[thread overview]
Message-ID: <20210503125446.1353307-2-mlevitsk@redhat.com> (raw)
In-Reply-To: <20210503125446.1353307-1-mlevitsk@redhat.com>

When forcibly leaving the nested mode, we should switch to vmcb01

Fixes: 4995a3685f1b ("KVM: SVM: Use a separate vmcb for the nested L2 guest")
