Russell,

will you take the all series from the git repository ? As the
last patches have been already acked-by Arnd and were initially pulled
by Jason Cooper, I think there should be no problem to get the whole
series.

Now if you only want to take the first three patches, will you pull
them from the git repository or do you prefer that I submit them
through your patch system?

Thanks,

Gregory
