Therefore it may work in cases where features.h is includes but not otherwise. Adding linux/stddef.h here ensures that __always_inline is always defined independent of which C library is used in userspace Signed-off-by: Khem Raj Cc: Philippe Ombredanne Cc: Kate Stewart Cc: Greg Kroah-Hartman Cc: Thomas Gleixner --- include/uapi/linux/swab.h | 1 + 1 file changed, 1 insertion(+) -- 2.20.0 diff --git a/include/uapi/linux/swab.h b/include/uapi/linux/swab.h index 23cd84868cc3..acddbe50a20d 100644 --- a/include/uapi/linux/swab.h +++ b/include/uapi/linux/swab.h @@ -3,6 +3,7 @@ #define _UAPI_LINUX_SWAB_H #include +#include #include #include
