+ * The cache counters use old counter values to calculate a hit ratio for each
+ * counter. The "cfg_wafl_t" struct therefore contains old counter values along
+ * with flags, which are set if the counter is valid.
+ *
+ * The function "cna_handle_wafl_data" will fill a new structure of this kind
+ * with new values, then pass both, new and old data, to "submit_wafl_data".
+ * That function calculates the hit ratios, submits the calculated values and
+ * updates the old counter values for the next iteration.
