{sigh}

None of these structures are valid ones to be passing to/from
userspace/kernel at all.  Please fix them up to work properly (i.e. use
the correct types and such).  I think there's a "how to write a correct
ioctl" document in the documentation directory somewhere, you might want
to search for that.
