Hi,
"This flag was deprecated from Linux 2.6.25 onward, and was removed altogether
in Linux 2.6.38."
As I understand, marking it as deprecated didn't prevent anyone from using it.
So, shouldn't the test still be valid up to 2.6.38, when it was finally removed?

I'd suggest to put the check directly to test_clone_stopped()
and you can avoid using checks that depend on order of testcases:
diff --git a/testcases/kernel/syscalls/clone/clone08.c
b/testcases/kernel/syscalls/clone/clone08.c
index 14ebf60..9518382 100644
