I didn't want to add everything before I got the core changes reviewed, commented and hopefully approved. Actually the ioctl to support creating new device partitions will be interesting because that will affect the size of the user area, so it would need to be rescanned. Obviously performing something like that on an MMC with a filesystem could be deleterious... What about hardware reset? It's more-or-less equivalent to powering off the bus from the SD controller... Why would you want to expose that through an ioctl?
