Heh, I know that, I wasn't asking a question.  I was saying that the assert should
tell the user/developer running the test why the count is "invalid", i.e. why the
assert failed.  Put yourself in the shoes of a random developer that's new to KVM
and knows almost nothing about dirty logging and isn't even aware PML is a thing.
Write the assert message for _that_ person.
