So my real questions are: Why do we have both kselftest and kunit?
What's the difference? Are there any plans to merge the two frameworks?
What's the point of converting from one to the other if not? And if one
is to take a currently stand-alone ad hoc test module and place it under
one of those umbrellas, which one should one choose?

I don't really care if the "deterministic random testing" prep work goes
with kstm or kunit; whichever framework could provide that boilerplate
is the framework I'd make sure to use for subsequent work on various tests.

The reporting of the number of "atoms" in the printf test suite is
something I'd miss if not preserved, but if there's sufficient good
rationale for doing the conversion to Kunit I could live with that. But
if kunit then can't provide a per-test-module rnd_state and handle its
seeding (and reporting of what seed was used), I won't ack the conversion.
