What I meant is: my prototype will include mtd_block, ftl for ssfdc, ftl for
memorystick, and backends for both adapted to work with fully callback driven
architecture. This is my current priority.

Everything else can be bolted on later.

(Current ssfdc.ko implementation is junk, sorry. Joern's driver has its own
implementation built-in).
