Zheng Yejian 394514ddf9 tracing: Fix issue of missing one synthetic field ... commit ff4837f7fe upstream. The maximum number of synthetic fields supported is defined as SYNTH_FIELDS_MAX which value currently is 64, but it actually fails when try to generate a synthetic event with 64 fields by executing like: # echo "my_synth_event int v1; int v2; int v3; int v4; int v5; int v6;\ int v7; int v8; int v9; int v10; int v11; int v12; int v13; int v14;\ int v15; int v16; int v17; int v18; int v19; int v20; int v21; int v22;\ int v23; int v24; int v25; int v26; int v27; int v28; int v29; int v30;\ int v31; int v32; int v33; int v34; int v35; int v36; int v37; int v38;\ int v39; int v40; int v41; int v42; int v43; int v44; int v45; int v46;\ int v47; int v48; int v49; int v50; int v51; int v52; int v53; int v54;\ int v55; int v56; int v57; int v58; int v59; int v60; int v61; int v62;\ int v63; int v64" >> /sys/kernel/tracing/synthetic_events Correct the field counting to fix it.
