Subject: [patch 60/86] arch: ipcbuf.h: make uapi asm/ipcbuf.h self-contained
Date: Wed, 04 Dec 2019 16:52:57 -0800	[thread overview]
Message-ID: <20191205005257.xpWzxf-9p%akpm@linux-foundation.org> (raw)
In-Reply-To: <20191204164858.fe4ed8886e34ad9f3b34ea00@linux-foundation.org>

From: Masahiro Yamada <yamada.masahiro@socionext.com>
Subject: arch: ipcbuf.h: make uapi asm/ipcbuf.h self-contained

Userspace cannot compile <asm/ipcbuf.h> due to some missing type
definitions.  For example, building it for x86 fails as follows:

  CC      usr/include/asm/ipcbuf.h.s
In file included from ./usr/include/asm/ipcbuf.h:1:0,
                 from <command-line>:32:

./usr/include/asm-generic/ipcbuf.h:31:2: error: unknown type name `__kernel_ulong_t'

  ^~~~~~~~~~~~~~~~
./usr/include/asm-generic/ipcbuf.h:32:2: error: unknown type name `__kernel_ulong_t'
  __kernel_ulong_t __unused2;
  ^~~~~~~~~~~~~~~~

It is just a matter of missing include directive.

Include <linux/posix_types.h> to make it self-contained, and add it to
the compile-test coverage.
