Like I said early it depends on the value you assign to significant. For a fs sizes I started designing to 16MB-64MB if you have to track a whole bunch of 8Byte numbers for every symlink, dev node, inode, and page. It adds up quickly to a couple of MB, that can translate to lots of money. Even at only an extra $0.25 a system * 12Million units = $3Million. -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
