* strlen_user: - Get the size of a string in user space.
* @str: The string to measure.

* Context: User context only. This function may sleep if pagefaults are
* enabled.

* Get the size of a NUL-terminated string in user space.
*
* Returns the size of the string INCLUDING the terminating NUL.
* On exception, returns 0.

* If there is a limit on the length of a valid string, you may wish to
* consider using strnlen_user() instead.
