mainline inclusion from mainline-5.14-rc2 commit e0fa7ab42232e742dcb3de9f3c1f6127b5adc019 category: bugfix bugzilla: 174605 https://gitee.com/openeuler/kernel/issues/I4DDEL
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
--------------------------------
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.
