Description

Shouldn't ptlrpc_obd_ping() issue a CERROR() before returning ENOMEM?

int ptlrpc_obd_ping(struct obd_device *obd)
{
        int rc;
        struct ptlrpc_request *req;
        ENTRY;

        req = ptlrpc_prep_ping(obd->u.cli.cl_import);
        if (req == NULL)
                RETURN(-ENOMEM); <========= HERE

        req->rq_send_state = LUSTRE_IMP_FULL;

        rc = ptlrpc_queue_wait(req);

        ptlrpc_req_finished(req);

        RETURN(rc);
}
