Subject: [PATCH 2/3] arch: msgbuf.h: make uapi asm/msgbuf.h self-contained
The user-space cannot compile <asm/msgbuf.h> due to some missing type
definitions. For example, building it for x86 fails as follows:
CC usr/include/asm/msgbuf.h.s
In file included from ./usr/include/asm/msgbuf.h:6:0,
from <command-line>:32:
./usr/include/asm-generic/msgbuf.h:25:20: error: field ‘msg_perm’ has incomplete type
struct ipc64_perm msg_perm;
^~~~~~~~
./usr/include/asm-generic/msgbuf.h:27:2: error: unknown type name ‘__kernel_time_t’
__kernel_time_t msg_stime; /* last msgsnd time */
^~~~~~~~~~~~~~~
./usr/include/asm-generic/msgbuf.h:28:2: error: unknown type name ‘__kernel_time_t’
__kernel_time_t msg_rtime; /* last msgrcv time */
^~~~~~~~~~~~~~~
./usr/include/asm-generic/msgbuf.h:29:2: error: unknown type name ‘__kernel_time_t’
__kernel_time_t msg_ctime; /* last change time */
^~~~~~~~~~~~~~~
./usr/include/asm-generic/msgbuf.h:41:2: error: unknown type name ‘__kernel_pid_t’
__kernel_pid_t msg_lspid; /* pid of last msgsnd */
^~~~~~~~~~~~~~
./usr/include/asm-generic/msgbuf.h:42:2: error: unknown type name ‘__kernel_pid_t’
__kernel_pid_t msg_lrpid; /* last receive pid */
^~~~~~~~~~~~~~
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.
