From 1ca5eebb894a3625b2a543c7b550aa4ae33ba3cc Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Fri, 24 Feb 2017 15:00:26 -0800 Subject: [PATCH] uapi: mqueue.h: add missing linux/types.h include Commit 63159f5dcccb ("uapi: Use __kernel_long_t in struct mq_attr") changed the types from long to __kernel_long_t, but didn't add a linux/types.h include. Code that tries to include this header directly breaks: /usr/include/linux/mqueue.h:26:2: error: unknown type name '__kernel_long_t' __kernel_long_t mq_flags; /* message queue flags */ This also upsets configure tests for this header: checking linux/mqueue.h usability... no checking linux/mqueue.h presence... yes configure: WARNING: linux/mqueue.h: present but cannot be compiled configure: WARNING: linux/mqueue.h: check for missing prerequisite headers? configure: WARNING: linux/mqueue.h: see the Autoconf documentation configure: WARNING: linux/mqueue.h: section "Present But Cannot Be Compiled" configure: WARNING: linux/mqueue.h: proceeding with the compiler's result checking for linux/mqueue.h... no Link: http://lkml.kernel.org/r/20170119194644.4403-1-vapier@gentoo.org Signed-off-by: Mike Frysinger Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/uapi/linux/mqueue.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/include/uapi/linux/mqueue.h b/include/uapi/linux/mqueue.h index d0a2b8e..bbd5116 100644 --- a/include/uapi/linux/mqueue.h +++ b/include/uapi/linux/mqueue.h @@ -18,6 +18,8 @@ #ifndef _LINUX_MQUEUE_H #define _LINUX_MQUEUE_H +#include + #define MQ_PRIO_MAX 32768 /* per-uid limit of kernel memory used by mqueue, in bytes */ #define MQ_BYTES_MAX 819200 -- 2.7.4
