    Fengguang,

    is there any chance we could start doing just the IO-less
    balance_dirty_pages, but not all the subtile other changes? I.e. are
    the any known issues that make things work than current mainline if we
    only put in patches 1 to 6? We're getting close to another merge
    window, and we're still busy trying to figure out all the details of
    the bandwith estimation. I think we'd have a much more robust tree
    if we'd first only merge the infrastructure (IO-less
    balance_dirty_pages()) and then work on the algorithms separately.
