Thanks for starting this off. We have several tests now and the number keeps growing.

I briefly looked at the get_size.c and have been thinking along the same lines that the get_size print routines could be leveraged and turned into common API in kselftest.h for all tests to use. It is the along the same lines as the direction this patch series takes.
