Without this patch fastmap can miss one PEB. As consequence of this during attach the fastmap self-check will detect this inconsistency and will fall back to a full scan. If you try to attach using a custom fastmap implementation (found in bootloaders) which do often not have sophisticated self-checks you'll face a serious data corruption or if you're lucky UBI will crash. Now clearer? :-) Thanks, //richard -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
