* value, otherwise it returns -EINVAL and *res is set to 0.
*
* 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.
*
* simple_strtoul just ignores the successive invalid characters and
* return the converted value of prefix part of the string.
