I'm curious what the stats are of code with the drivers removed. Code growth through drivers
and archs that 95% people of people won't run in their kernel isn't that interesting.
I have a vague feeling (without proof) that the core kernel sans drivers is not growing that
dramatically. Subsystems already have their own maintainers and review systems.
Scaling then happens with the splitting into subsystems and driver maintainers, etc. So not
actually a problem in the longer term, even though total LoC churn would be very high.
