Subject: [PATCH 3/3] arch: sembuf.h: make uapi asm/sembuf.h self-contained
Date: Wed, 30 Oct 2019 15:38:55 +0900	[thread overview]
Message-ID: <20191030063855.9989-3-yamada.masahiro@socionext.com> (raw)
In-Reply-To: <20191030063855.9989-1-yamada.masahiro@socionext.com>

The user-space cannot compile <asm/sembuf.h> due to some missing type
definitions. For example, building it for x86 fails as follows:

  CC      usr/include/asm/sembuf.h.s
In file included from <command-line>:32:0:
./usr/include/asm/sembuf.h:17:20: error: field ‘sem_perm’ has incomplete type
  struct ipc64_perm sem_perm; /* permissions .. see ipc.h */
                    ^~~~~~~~
./usr/include/asm/sembuf.h:24:2: error: unknown type name ‘__kernel_time_t’
  __kernel_time_t sem_otime; /* last semop time */
  ^~~~~~~~~~~~~~~
./usr/include/asm/sembuf.h:25:2: error: unknown type name ‘__kernel_ulong_t’
  __kernel_ulong_t __unused1;
  ^~~~~~~~~~~~~~~~
./usr/include/asm/sembuf.h:26:2: error: unknown type name ‘__kernel_time_t’
  __kernel_time_t sem_ctime; /* last change time */
  ^~~~~~~~~~~~~~~
./usr/include/asm/sembuf.h:27:2: error: unknown type name ‘__kernel_ulong_t’
  __kernel_ulong_t __unused2;
  ^~~~~~~~~~~~~~~~
./usr/include/asm/sembuf.h:29:2: error: unknown type name ‘__kernel_ulong_t’
  __kernel_ulong_t sem_nsems; /* no. of semaphores in array */
  ^~~~~~~~~~~~~~~~
./usr/include/asm/sembuf.h:30:2: error: unknown type name ‘__kernel_ulong_t’
  __kernel_ulong_t __unused3;
  ^~~~~~~~~~~~~~~~
./usr/include/asm/sembuf.h:31:2: error: unknown type name ‘__kernel_ulong_t’
  __kernel_ulong_t __unused4;
  ^~~~~~~~~~~~~~~~

It is just a matter of missing include directive.

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