Wong <darrick.wong@xxxxxxxxxx> I'm not sure that we need this patch. If someone explicitly requests a r/w mount of an ext3 file system using ext2, we should let it. After changing the default probe order, the only time your change would prohibit the mounting of an ext3 file system is when the system administrator has explicitly mentioned the file system type in command line. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
