I'm really sorry to make this trouble. And I'm OK to revert the patch.
I just a little wondering how do you generate this script.
I tested with 'make -C tools/testing/selftests gen_tar FORMAT=.xz' before
post the patch and all looks good to me.

```

run_seccomp()
{
        [ -w /dev/kmsg ] && echo "kselftest: Running tests in seccomp" >> /dev/kmsg
        cd seccomp
        run_many        \
                "seccomp_bpf"   \
                "seccomp_benchmark"
        cd $ROOT
}

```

Thanks
