Miklos Szeredi 1dc1eed46f ovl: fix IOCB_DIRECT if underlying fs doesn't support direct IO ... Normally the check at open time suffices, but e.g loop device does set IOCB_DIRECT after doing its own checks (which are not sufficent for overlayfs). Make sure we don't call the underlying filesystem read/write method with the IOCB_DIRECT if it's not supported.
