Andrew Morton 016eb4a0ed [PATCH] invalidate_complete_page() race fix ... If a CPU faults this page into pagetables after invalidate_mapping_pages() checked page_mapped(), invalidate_complete_page() will still proceed to remove the page from pagecache. This leaves the page-faulting process with a detached page. If it was MAP_SHARED then file data loss will ensue. Fix that up by checking the page's refcount after taking tree_lock.
