Hi, In August 2010, Jens and Alan discussed about "Runtime PM and the block layer". http://marc.info/?t=128259108400001&r=1&w=2 Here are the very draft, compile tested only patches that try to implement the ideas discussed. I throw it out early to get feedbacks and see if I'm on the right direction.
