Am I right that the appropriate transformation is:
        rc = rcu_lock_target_domain_by_id(domid, &d);
becomes:
        d = rcu_lock_domain_by_any_id(a.domid);
        if ( d == NULL )
            return -ESRCH;

        rc = xsm_SOMETHING(XSM_TARGET, d, PARAMS);
        if ( rc )
            ... unlock .. return or goto err

Ian.
