In original source a c function have this signature:

static inline __attribute__((always_inline)) unsigned long
__attribute__((warn_unused_result)) copy_from_user(void *to, const void *from,
unsigned long n)

but putting back inline or __attribute__((always_inline)) (or both) do not
change anything.
