Add test to assert that we have now allowed merging of VMAs when KSM merging-by-default has been set by prctl(PR_SET_MEMORY_MERGE, ...). We simply perform a trivial mapping of adjacent VMAs expecting a merge, however prior to recent changes implementing this mode earlier than before, these merges would not have succeeded. Assert that we have fixed this!
