From 9708dc74d9f49488d669e070982f6224a888d61a Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Wed, 12 Sep 2018 17:08:58 -0700 Subject: [PATCH] include linux/stddef.h in swab.h uapi header swab.h uses __always_inline without including the header where it is defined, this is exposed by musl based distributions where this macro is not defined by system C library headers unlike glibc where it is defined in sys/cdefs.h and that header gets pulled in indirectly via features.h -> sys/cdefs.h and features.h gets pulled in a lot of headers. 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 Upstream-Status: Submitted [https://lkml.org/lkml/2018/9/13/78] 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(+) 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 -- 2.19.0
