This macro NSEC_PER_SEC is never referenced in the code. Just remove it.

Is this duplicate patch?

I think I commented on your patch on futex - include how you found the problem in change logs. Also you have to include subsystem prefix in the subject line:

selftests/timers: Remove unused NSEC_PER_SEC macro

I see another patch with similar problems from you. Refer to submitting patches document in the kernel repo.
