- * strict_strtoul - convert a string to an unsigned long strictly

- * @res: The converted result value
- *
- * strict_strtoul converts a string to an unsigned long only if the
- * string is really an unsigned long string, any string containing
- * any invalid char at the tail will be rejected and -EINVAL is returned,
- * only a newline char at the tail is acceptible because people generally
- * change a module parameter in the following way:
- *
- * echo 1024 > /sys/module/e1000/parameters/copybreak
- *
- * echo will append a newline to the tail.
- *
- * It returns 0 if conversion is successful and *res is set to the converted
- * value, otherwise it returns -EINVAL and *res is set to 0.
- *
- * simple_strtoul just ignores the successive invalid characters and
- * return the converted value of prefix part of the string.
