                timeout.tv_sec = now.tv_sec + MAX_FUSE_PROC_DELAY;
                timeout.tv_nsec = now.tv_usec * 1000;

                        ret = pthread_cond_timedwait (&priv->child_up_cond,
                                                &priv->child_up_mutex,
                                                &timeout);
                        if (ret != 0)
                                break;

                }
        }
        pthread_mutex_unlock (&priv->child_up_mutex);

        gf_log (this->name, GF_LOG_DEBUG,
                " pthread_cond_timedout returned non zero value"
                " ret: %d errno: %d", ret, errno);


In the above code even the return value of pthread_cond_timeout is zero, the log message will be displayed as "pthread_cond_timedout returned non zero value" as it will be always executed after the unlock.
