The function security_path_chown arg1 type STRUCT is unsupported.

Nobody has claimed this yet.

```python
#!/usr/bin/python

from bcc import BPF

bpf_text = '''
KFUNC_PROBE(security_path_chown, struct path *path)
{
return 0;
}
'''

b = BPF(text=bpf_text)
print("BPF programs loaded")
b.trace_print()

```

This small program failed with the following error messages:

```
bpf: Failed to load program: Invalid argument
The function security_path_chown arg1 type STRUCT is unsupported.
processed 0 insns (limit 1000000) max_states_per_insn 0 total_states 0 peak_states 0 mark_read 0
```

Did not figure out what causes this error. Changing the function `security_path_chown` to `security_path_chmod` works fine.

Run the provided Python BCC reproducer with the security_path_chown KFUNC_PROBE and compare it with the working security_path_chmod case. Trace where BCC or its BPF argument handling rejects STRUCT arguments, then verify that the reproducer loads successfully and the unsupported-argument error is covered by a regression test.
