Description

In lmv_revalidate_slaves() it may happen that md_intent_lock() fails but leaves us with a reference to the request. In this case the request will be leaked:

                rc = md_intent_lock(tgt->ltd_exp, op_data, &it, &req,
                                    cb_blocking, extra_lock_flags);
                if (rc < 0)
                        GOTO(cleanup, rc);

                ...

cleanup:
        OBD_FREE_PTR(op_data);
        RETURN(rc);
}
