kprobe_events are not available (seems related to CONFIG_KALLSYMS disabled) and this test `tools/testing/selftests/ftrace/test.d/dynevent/test_duplicates.tc` doesn't seems to works well in this case as it fails quickly: ``` + echo e:egroup/eevent syscalls/sys_enter_openat file=+0($filename):ustring ./ftracetest: 18: echo: echo: I/O error ```
