Matthew Wilcox (Oracle) 4612aeef09 mm/filemap: convert filemap_update_page to return an errno
Use AOP_TRUNCATED_PAGE to indicate that no error occurred, but the page we
looked up is no longer valid.  In this case, the reference to the page
will have been removed; if we hit any other error, the caller will release
the reference.
