Correct.

Blast... I made the change on top of a much more recent kernel, and I guess my
patches don't apply. You should be able to do this test on top of a recent
kernel -- e.g. 3.10, or 3.11-rc2. You can get this by just doing "git checkout
master" (or "origin" instead of "master", I forget)

Alternatively you could look at where I put the prints in and plop them in
manually. I guess the classy thing for me to do would be to create a debugging
patch that'll apply to that revision... perhaps I'll do that later if you run
into trouble with this or the results are nonsensical.
