OK.

In your patches I do not see why these ioctl's are enabled only if the
CONFIG_MTD_UBI_DEBUG_USERSPACE_IO configuration option is switched on.
It looks like the ioctl's are always enabled.
Well, you probably also need direct LEB write functionality, which is
present only as a debugging option so far. We may make it non-debugging
at some point, I guess. The reason why we disabled this is because we
wanted to prevent dump users from doing stupid things.
