Instead of using a falco_rule struct on the stack, use a single value inside the falco_source struct. It's mutable as find_source returns a const struct. At very high event volumes (> 1M syscalls/second), even the tiny time it takes to create/destroy the struct starts to add up, and this switch has some small cpu savings.
