Subject: [PATCH 1/8] KVM: SVM: rename a variable in the svm_create_vcpu
Date: Thu, 20 Aug 2020 12:13:20 +0300 [thread overview]
Message-ID: <20200820091327.197807-2-mlevitsk@redhat.com> (raw)
In-Reply-To: <20200820091327.197807-1-mlevitsk@redhat.com>
The 'page' is to hold the vcpu's vmcb so name it as such to
avoid confusion.
