It's correct - but triggers plenty of extra warnings and you forgot about
get_user() which has the same kind of issue.  Also you don't have the
guarantee that <linux/types.h> has been included, so in order to avoid a
yet another header file dependency I changed s8, s16 etc. to char, short,
int, long long.  Working on it but as usual uaccess.h is quite a quiz.
