If I use:
module_param_named(bpf.sig_enforce, sig_enforce, bool_enable_only, 0644);
It explodes and if I do as before:
module_param(sig_enforce, sig_enforce, bool_enable_only, 0644);
Then it ends up as 'syscall.sig_enforce'.
The closest I got so far was:

Hi Masami,
Any idea why listing the source code doesn't work while simply
adding the probe works?
[root@seventh ~]# perf probe verify_pkcs7_signature
Added new event:
probe:verify_pkcs7_signature (on verify_pkcs7_signature)
You can now use it in all perf tools, such as:
perf

- Use proper CPU for shadow stats in 'perf stat'.
- Update copy of libbpf's hashmap.c, silencing tools/perf build warning.
- Fix return value in 'perf diff'.
