There aren't very many and they do very discrete things. The big part that may change is the device scanning, which may get more integrated into udev and mount (see other threads about this). But, that is one very simple ioctl, and most of the code it uses is going to stay regardless of how the device scanning is done. -chris -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
