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
