How much of this is just the added instrumentation? Because that's
almost a thousand new lines, which makes me unhappy. The *last* thing
we want is to make this thing bigger. I'm not convinced it's worth it
adding some performance debug code that doesn't really add any new
information, and could be done outside the kernel as just an
independent module instead.
