Steve,

Do you want to make a call on which one you want me to take it
through between these two patches - one from Dave and the other
from Namhyung Kim.

Please send me the patch I have to pull in. Namhyung Kim's patch
isn't in the format I can apply and I don't have Dave's patch in
my inbox.

thanks,
-- Shuah
