Subject: [PATCH 10/24] KVM: nSVM: pass vmcb_control_area to copy_vmcb_control_area
Date: Wed, 20 May 2020 13:21:31 -0400 [thread overview]
Message-ID: <20200520172145.23284-11-pbonzini@redhat.com> (raw)
In-Reply-To: <20200520172145.23284-1-pbonzini@redhat.com>
This will come in handy when we put a struct vmcb_control_area in
svm->nested.
