The "Variable > Block Flash" component is *not* a filesystem. It simply translates > logical sector requests to physical flash locations. Similar in principle, then, if not in implementation, to FTL. A kind of pseudo-filesystem which is used to emulate a block device. Does it use the concepts which are patented by M-Systems? I believe that the patents in this area are extremely broad, and cover almost all obvious methods of implementing wear levelling. -- dwmw2 To unsubscribe, send "unsubscribe mtd" to majordomo@infradead.org
