Description

Unlikely to be hit in real world, but there's a potential memory leak in lnet_peer_data_present. If the ping buffer has nnis <= 1 then function is exited without dropping the ref on the ping buffer causing this memory to leak:

        if (pbuf->pb_info.pi_nnis <= 1)
                goto out;
