Too bad you don't have a more descriptive name for it, UBI just doesn't seem to have any connection to LVM for Flash plus wear leveling. /grin/ John - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
