Tejun Heo 0feacaa216 writeback: don't access page->mapping directly in track_foreign_dirty TP ... page->mapping may encode different values in it and page_mapping() should always be used to access the mapping pointer. track_foreign_dirty tracepoint was incorrectly accessing page->mapping directly. Use page_mapping() instead. Also, add NULL checks while at it.
