No, the system calls are as far as I know fine, it is just that pioctl
uses ioctl, which doesn't interpret the contents of the blobs it passed
back and forth.

And cfs/venus probably use long integers in some of the structures, so a
32-bit cfs binary cannot talk to a 64-bit venus and vv. Or maybe in some
cases we might have a collision with a 'legacy ioctl' and the kernel
might have do that tries to interpret and translate it, but I doubt that.
