Perhaps this becomes rather fragile code overly dependent on the current #define values of LOAD_AVG_MAX_N and LOAD_AVG_PERIOD. Perhaps this comment just above the definitions of LOAD_AVG_MAX_N and LOAD_AVG_PERIOD should be updated to include this new table: * Note: The tables runnable_avg_yN_inv and runnable_avg_yN_sum are * dependent on this value. Perhaps the __ prefix for __accumulated_sum_N32 is odd as both of the runnable_avg_yN_ tables are not __ prefixed.
