NACK
Moving via pointers - thus you need to check whether pointer passes
array boundary (just like C++ vector() iterator)
see the difference:
for(req = 0; i < sizeof(requests) / sizeof(requests[0]); req++0

Ahh, I've confused myself.
as req is pointer of the same type, pointer arithmetic applies here as well,
so the patch is correct. We need to add number of array elements.
