Redundancy is not an issue (sometimes it is a virtue, the slight
variations in test setup lead to wider coverage and serendipity - when we
don't have a fuzzer, we have to rely on random variations between
authors). The purpose of each test is different, one is testing prime and
interactions with i915 on/from a foreign bo; the other looking at
pwrite/pread in depth. Each subtest is meaningful as part of the
encompassing test.

The counter proposal is to be able to select a cross-selection of
subtests for a given set of tags/functions/code. And we still need a
fuzzer, model based or not.
