Hi,
The updated membarrier tree: https://github.com/compudj/linux-dev branch: sys-membarrier-volatile
has an issue building selftests (make -C tools/testing/selftests)
It appears that including linux/membarrier.h from those userspace tests now fails (as of 4.1-rc8). Of course, my system does not have the updated userspace headers installed. What is the right course of action there ?
[...] gcc -I../../../../usr/include/ kcmp_test.c -o kcmp_test kcmp_test.c:13:24: fatal error: linux/kcmp.h: No such file or directory #include <linux/kcmp.h> ^ compilation terminated. make[1]: *** [kcmp_test] Error 1 make[1]: Leaving directory `/home/efficios/git/linux-dev/tools/testing/selftests/kcmp' make[1]: Entering directory `/home/efficios/git/linux-dev/tools/testing/selftests/membarrier' gcc -g -I../../../../usr/include/ membarrier_test.c -o membarrier_test membarrier_test.c:4:30: fatal error: linux/membarrier.h: No such file or directory #include <linux/membarrier.h> ^ compilation terminated. make[1]: *** [all] Error 1 make[1]: Leaving directory `/home/efficios/git/linux-dev/tools/testing/selftests/membarrier' make[1]: Entering directory `/home/efficios/git/linux-dev/tools/testing/selftests/memfd' gcc -D_FILE_OFFSET_BITS=64 -I../../../../include/uapi/ -I../../../../include/ -I../../../../usr/include/ memfd_test.c -o memfd_test memfd_test.c: In function ‘sys_memfd_create’: memfd_test.c:26:17: error: ‘__NR_memfd_create’ undeclared (first use in this function) return syscall(__NR_memfd_create, name, flags); ^ memfd_test.c:26:17: note: each undeclared identifier is reported only once for each function it appears
Thanks,
