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.
