I hope the recent rework of the unit test can help having more of these
unit tests into the kselftests directly.

Currently it's still ugly even after the rework patchset - we'll need to
reference e.g. area_dst in unit tests for the allocated memory region (with
specified type of either MEM_ANON, MEM_SHMEM, ...), but there's plan to
make it even better.

Thanks for fixing those already.
