Reading http://www.linux-mtd.infradead.org/faq/jffs2.html, it says that jffs2 can be mounted with or without the mtdblock driver. Eg: mount -t jffs2 mtd2 /foo vs mount -t jffs2 /dev/mtdblock2 /foo I'm wondering what is the difference between these two methods with respect to performance? Thanks, Dave
