Jens Axboe 985b71db17 iomap: use filemap_range_needs_writeback() for O_DIRECT reads ... For reads, use the better variant of checking for the need to call filemap_write_and_wait_range() when doing O_DIRECT. This avoids falling back to the slow path for IOCB_NOWAIT, if there are no pages to wait for (or write out).
