writeback: do uninterruptible sleep in balance_dirty_pages()
 
Using TASK_INTERRUPTIBLE in balance_dirty_pages() seems wrong.  If it's
going to do that then it must break out if signal_pending(), otherwise
it's pretty much guaranteed to degenerate into a busywait loop.  Plus we
*do* want these processes to appear in D state and to contribute to load
average.

So it should be TASK_UNINTERRUPTIBLE.                 -- Andrew Morton
