From 7685ab6c58557c6234f3540260195ecbee7fc4b3 Mon Sep 17 00:00:00 2001 From: Chunyu Hu Date: Tue, 5 Sep 2017 13:36:46 +0800 Subject: tracing: Fix clear of RECORDED_TGID flag when disabling trace event When disabling one trace event, the RECORDED_TGID flag in the event file is not correctly cleared. It's clearing RECORDED_CMD flag when it should clear RECORDED_TGID flag.
