[PATCH] tracing: Fix clear of RECORDED_TGID flag when disabling trace event

From: Chunyu Hu
Date: Tue Sep 05 2017 - 01:37:02 EST


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. Fix d914ba37("tracing: Add support
for recording tgid of tasks")
