These four lines are a bit repeated. Perhaps change them to
if (enable_shadow_vmcs || vmx->nested.hv_evmcs)
vmx->nested.need_vmcs12_sync = true;
and elsewhere
if (vmx->nested.need_vmcs12_sync) {
if (vmx->nested.hv_evmcs) {
copy_vmcs12_to_enlightened(vmx);
/* All fields are clean */
vmx->nested.hv_evmcs->hv_clean_fields |=
HV_VMX_ENLIGHTENED_CLEAN_FIELD_ALL;
vmx->nested.sync_enlightened_vmcs = false;
} else {
copy_vmcs12_to_shadow(vmx);
}
vmx->nested.need_vmcs12_sync = false;
}
?
