I think this issue should be closed @acassis

@PiyushPatle26 but #2375 wasn't integrated. Is there some another Spinlock tester?

[PiyushPatle26]

@acassis After looking at the current testing/ostest/ directory, spinlock.c is already present and included in both Makefile and CMakeLists.txt

@PiyushPatle26 true! Although the code are different, the goal of this Issue here was met!
