Revision 659ede7d13f1cc37882088deecbc085da285b8f8 authored by Riccardo Mancini on 15 July 2021, 16:07:23 UTC, committed by Arnaldo Carvalho de Melo on 15 July 2021, 20:35:57 UTC
ASan reports several memory leaks running: # perf test "88: Check open filename arg using perf trace + vfs_getname" The fourth of these leaks is related to some strings never being freed in trace__parse_events_option. This patch adds the missing frees.
