This is not a regression, I can see this issue with 5.15.0-30.31 as well.
We just don't have a bug report for this.

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
```

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
