No.

include/linux/types.h:typedef __kernel_size_t           size_t;

include/uapi/asm-generic/posix_types.h:

#ifndef __kernel_size_t
#if __BITS_PER_LONG != 64
typedef unsigned int    __kernel_size_t;
#else
typedef __kernel_ulong_t __kernel_size_t;
#endif
#endif

size_t is an unsigned long on 64-bit, unless otherwise defined by the
arch.
