    The code is easily changed because it is private to Smack and we don't have to
    worry about backwards compatibility issues. I would focus on improving the
    linked list approach (masked, sorted, etc.) and when traversing the list
    becomes a bottleneck we can look at alternative approaches. Others may have a
    better view, but from what I've seen the general approach taken in Linux
    Kernel optimization is to develop something that works then refine and
    optimize it once you have a better understanding of the common use cases.
