One topic that I think that might be interesting is to talk about how 
well we did integrating all of these new features into the stack that 
cross IO/FS/scheduler boundaries. In a way, we got ahead of the hardware 
vendors with both the discard support and the various topology bits but 
did manage to get that supported not just in the kernel but up the tool 
chain as well.

Might be interesting to see where we ended up, think about next steps 
and if/how we would improve on what we have....
