Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The function `kmod_dup_request_exists_wait()` mixes `goto`-based error/cleanup handling with `scoped_guard()` declarations, violating subsystem guidelines.

module/dups: Clean up includes

This patch cleans up the #include directives in kernel/module/dups.c.
It explicitly includes the headers for all definitions and functions
relied upon by the file.

[Severity: Low]
Does kmod_dup_request_exists_wait() violate the cleanup subsystem guidelines
by mixing goto labels and scoped_guard() declarations?

kernel/module/dups.c:kmod_dup_request_exists_wait() {
	...
	scoped_guard(mutex, &kmod_dup_mutex) {
		kmod_req = kmod_dup_request_lookup(module_name);
		if (kmod_req) {
			get_kmod_req(kmod_req);
			goto dup_req;
		}
		...
	}
	...
dup_req:
	...
	if (!wait) {
		...
		goto out;
	}
	...
out:
	put_kmod_req(kmod_req);
	return true;
}

The cleanup subsystem guidelines expect that usage of goto and cleanup
helpers are never mixed in the same function.
