This change breaks seccomp build:

make -C tools/testing/selftests/seccomp/
make: Entering directory '/mnt/data/lkml/linux_4.12/tools/testing/selftests/seccomp'
make: *** No rule to make target '../kselftest_harness.h', needed by '/mnt/data/lkml/linux_4.12/tools/testing/selftests/seccomp/seccomp_bpf'.  Stop.
make: Leaving directory '/mnt/data/lkml/linux_4.12/tools/testing/selftests/seccomp'
shuah@mazurka:/mnt/data/lkml/linux_4.12$ cd tools/testing/selftests/seccomp/
shuah@mazurka:/mnt/data/lkml/linux_4.12/tools/testing/selftests/seccomp$ make
make: *** No rule to make target '../kselftest_harness.h', needed by '/mnt/data/lkml/linux_4.12/tools/testing/selftests/seccomp/seccomp_bpf'.  Stop.


Did you happen to try building with this change?

thanks,
