That's because stdio.h is a C library header. You can't use the C
library in the kernel.

You should actually be able to include string.h, but you need the kernel
version, which lives in include/linux/string.h.
The kernel provides a few of the functions usually provided by the C
library. Things like memcpy() and memset() exist. printf() doesn't, but
there is an sprintf(), ...
