Thanks for the patch Anders. Tested-by: Naresh Kamboju naresh.kamboju@linaro.org
Did something change recently? This has built fine on arm64 for a while -- at least since commit 256d0afb11d6 ("selftests/seccomp: build and pass on arm64").
Ah, found it. I broke it in a33b2d0359a0! :) Shuah, can you take this please, with this tag added:
Fixes: a33b2d0359a0 ("selftests/seccomp: Add tests for basic ptrace actions")
And Cc to stable, as this was broken in 4.14...
Cc: stable@vger.kernel.org

Thanks Kees. Yes I will get this into 4.16-rc1. Okay to add your Acked-by I assume.
Yes, thanks! Here it is all together:

Applied to linux-kselftest next for 4.16-rc1
