Can you add this at the head of the series? It will help with proving that the test case fails and hence we need subsequent fixes.

Can you convert the above into a function like 'test_ring_mem_reset'?

^^^^^^ This does not create an unaligned address. You have to use the typecasting to 'char *' like in the original code.
