in query cache information plugin file (qc_info.cc), line 69:

{"RESULT_BLOCKS_COUNT", MY_INT32_NUM_DECIMAL_DIGITS, MYSQL_TYPE_LONG, 0, 0, 0, 0},

{"RESULT_BLOCKS_SIZE", MY_INT32_NUM_DECIMAL_DIGITS, MYSQL_TYPE_LONGLONG, 0, 0, 0, 0},

why we use the same "MY_INT32_NUM_DECIMAL_DIGITS" for "MYSQL_TYPE_LONG" and "MYSQL_TYPE_LONGLONG" ?
