Subject: [PATCH 2/6] shmbuf.h: add asm/shmbuf.h to UAPI compile-test coverage
asm/shmbuf.h is currently excluded from the UAPI compile-test because of
the errors like follows:
HDRTEST usr/include/asm/shmbuf.h
In file included from ./usr/include/asm/shmbuf.h:6,
from <command-line>:
./usr/include/asm-generic/shmbuf.h:26:33: error: field ‘shm_perm’ has incomplete type
26 | struct ipc64_perm shm_perm; /* operation perms */
| ^~~~~~~~
./usr/include/asm-generic/shmbuf.h:27:9: error: unknown type name ‘size_t’
27 | size_t shm_segsz; /* size of segment (bytes) */
| ^~~~~~
./usr/include/asm-generic/shmbuf.h:40:9: error: unknown type name ‘__kernel_pid_t’
40 | __kernel_pid_t shm_cpid; /* pid of creator */
| ^~~~~~~~~~~~~~
./usr/include/asm-generic/shmbuf.h:41:9: error: unknown type name ‘__kernel_pid_t’
41 | __kernel_pid_t shm_lpid; /* pid of last operator */
| ^~~~~~~~~~~~~~
The errors can be fixed by replacing size_t with __kernel_size_t and by
including proper headers.
Then, remove the no-header-test entry from user/include/Makefile.
