Nick Piggin 79352894b2 mm: fix clear_page_dirty_for_io vs fault race ...

Fix msync data loss and (less importantly) dirty page accounting
inaccuracies due to the race remaining in clear_page_dirty_for_io().

The deleted comment explains what the race was, and the added comments
explain how it is fixed.
