KVM: SVM: Add a comment to clarify what vcpu_svm.vmcb points at
Add a comment above the declaration of vcpu_svm.vmcb to call out that it is simply a shorthand for current_vmcb->ptr. The myriad accesses to svm->vmcb are quite confusing without this crucial detail. No functional change intended. Signed-off-by: Sean Christopherson <seanjc@google.com> Message-Id: <20210406171811.4043363-4-seanjc@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
