From: Riccardo Mancini <rickyman7@gmail.com> stable inclusion from linux-4.19.199 commit 63b823ae24cc85cf718fd08e2834d47c60554f50 -------------------------------- [ Upstream commit e0fa7ab42232e742dcb3de9f3c1f6127b5adc019 ] ASan reports some memory leaks when running: # perf test "42: BPF filter" This second leak is caused by a strlist not being dellocated on error inside probe_file__del_events. This patch adds a goto label before the deallocation and makes the error path jump to it.
