Thanks Kemeng for the cleanup series. Looks good to me with few minor
nits which I have commented in individual patches.

Note that I couldn't cleanly apply the series on ted's dev branch
(Patch-05 gave some minor conflict). Maybe you might have based your
changes on top of linux master or something. Anyways it was just a minor
conflict and I don't know what is Ted's general preference here, but I
thought of doing an FYI -
