Hi SeongJae,

You keep doing good jobs ;)

I believe it would be better if you consider the little things below
more. What do you think about it, SeongJae?

     See the subsection "Kernel I/O barrier effects" for more information on
     relaxed I/O accessors and the Documentation/DMA-API.txt file for more
     information on consistent memory.
