I think it will be useful to do that, yes, but as the tests are currently a skeleton to both provide the stubbing out and to provide essentially an example of how you might test (though enough that it'd now be easy to add a _ton_ of tests), it's not quite ready to be run just yet. > > > 51 files changed, 3914 insertions(+), 2453 deletions(-) > > eep.

Argh. Well, the numbers are scary, but it's _mostly_ moving code around with some pretty straightforward refactorings and adding a bunch of userland code that won't impact kernels at all. So I'd argue this is less crazy in size than it might seem...
