The change from Thomas Gleixner which enables us to write mulitple times to a NAND page would also be very helpful too. We can put the UBI EC header (for the erase count) and the VID hdr (volume information header) into the same page. If we would have those two changes, others like Kyungmin and Marteo could start making use of UBI. I really hope that we get those changes in the ubi-2.6.git as soon as possible. Frank
