I still do not get why can't the kernel __u64 match the uint64_t at least in userspace. It should be as easy as: diff --git a/include/uapi/asm-generic/types.h b/include/uapi/asm-generic/types.h index dfaa50d99d8f..3c9a1fc5d5c3 100644 --- a/include/uapi/asm-generic/types.h +++ b/include/uapi/asm-generic/types.h @@ -2,8 +2,12 @@ #ifndef _ASM_GENERIC_TYPES_H #define _ASM_GENERIC_TYPES_H /* - * int-ll64 is used everywhere now. + * int-ll64 is used everywhere in kernel now. */ -#include <asm-generic/int-ll64.h> +#if __BITS_PER_LONG == 64 && !__KERNEL__ +# include <asm-generic/int-l64.h> +#else +# include <asm-generic/int-ll64.h> +#if #endif /* _ASM_GENERIC_TYPES_H */ -- Cyril Hrubis chrubis@xxxxxxx
