Then, we can develop an ext4 driver that understands the new format. --=-g6OuHrULNGwkTGEi2NHq Content-Type: application/pgp-signature; name=signature.asc Content-Description: Esta parte del mensaje =?ISO-8859-1?Q?est=E1?= firmada digitalmente -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iQIVAwUASGfYeqSl+Fbdeo72AQKtWQ/9Ful/arhvBXm1cE7gwdzGgMKtWEJfkLqQ MtYMs/LFLTMTckQBZiu1jcbXzgQ4j9G621emXHYn5rvdqAFqJ9KZDEZIJsae3gaW mQyyPBtFy03UOKN1gdujYVILjpQAvWg/OqtLxLD04KfWPGwcqbDvifmKxXhhWuT/ DZ1i6xqoB8RcQ+0qsmNFQkQnVcgGfpYeLYQ6vqBP/Yq6841JFKEFzOdCDEjMNyVH PDTb4d8uYiRhfBs2OVz2QAjp2K5278Lk1Wy+JOQ7GkupOzDkWIy9js7SxMW2tAjT 26vvxXIJewMme8c/KEumliBK6JTzMywbzhYzfXx8bpmEw8ZLxq3EsvaLMRTKjap/ 8x43BtFFwuC+oj0osSe5WWOrCia2tTSBV0zJFpiAo9MZXY1XQRpjmy/K4o1reM2z HPWA8/SPtthwh6+sB6qamVfeEMq7P9/SrTQGARUU1Ikmw5KO3Pb9RJefrYihl1LG b76GV7Ycpn1+do2pWoOw4XuLpIKJy/WiJt4G9OlxVTMfPJrFUjiRSy4N1dyqyU2m PXOcV9TrgndNeM8E42PK1WEMWEOGcpuG16BkIkEhYZisp3bSwFRCM1/60TZ+S7dC spKcDl+NQzEFGyBpdzDufl5n7x0DjVHdsa1MnZJ0S3bJMvd/VXVgrSm9b6croDlv H4CTi7HtNwU= =GBBC -----END PGP SIGNATURE----- --=-g6OuHrULNGwkTGEi2NHq--
