#include<string.h> actually refers to /usr/include/string.h present on
the system whereas
#include<linux/string.h> refers to
/usr/src/linux-headers-2.6.35-22-generic/include/linux/string.h if
your linux kernel version is 2.6.535.22 or to corresponding kernel
directory you have targeted the compiler to.

linux/string.h contains functions optimized for kernel but I still
dont understand why does it still include string.h.
