-/**
- * @brief
- * The object that is in the data-path to perform the check.
- *
- * Some trade-offs here; memory vs performance.
- *
- * performance:
- * the principle factor is d-cache line misses/hits.
- * so we want the data layout to minimise the d-cache misses. This
- * means not following dependent reads. i.e. not doing
- *
- * struct B {
- * u16 n_ranges;
- * range_t *ragnes; // vector of ranges.
- * }
- *
- * so to read ranges[0] we would first d-cache miss on the address
- * of the object of type B, for which we would need to wait before we
- * can get the address of B->ranges.
- * So this layout is better:
- *
- * struct B {
- * u16 n_ranges;
- * range_t ragnes[N];
- * }
- *
- * memory:
- * the latter layout above is more memory hungry. And N needs to be:
- * 1 - sized for the maximum required
- * 2 - fixed, so that objects of type B can be pool allocated and so
- * 'get'-able using an index.
- * An option over fixed might be to allocate contiguous chunk from
- * the pool (like we used to do for multi-path adjs).
