In that case, we don't need to pass the list_head. - If the purpose is just counting the number of matched entries (or just checking existence), we also don't need the list. Just returning the number is enough.I recommend you to remove the "sdt_notes", and make the caller check key->addr is set.
Yeah, list isn't required in this case. Thanks for pointing that out. Will change that.
