The compute_generation_info code uses function pointers to abstract the get/set generation operations. Some callers don't need the extra void data pointer, which should be annotated to appease -Wunused-parameter. Note that we can drop the assignment of the "data" parameter in compute_generation_numbers(), as we've just shown that neither of the callbacks it uses will access it. This matches the caller in ensure_generations_valid(), which already does not bother to set "data".
