[PATCH 11/20] perf session: cleanup trace_event

From: Riccardo Mancini
Date: Thu Jul 15 2021 - 12:07:57 EST


ASan reports several memory leaks when running the perf test
"82: Use vfs_getname probe to get syscall args filenames", many of which
are related to session->tevent.
This patch will solve this problem, then next patch will fix the remaining
memory leaks in perf-script.
This bug is due to a missing deallocation of the trace_event data
strutures.

This patch adds the missing trace_event__cleanup in
perf_session__delete.
