If we add it now without extensibility code, we will have a kernel that only knows the
ioctl with the size as it is now. If we later add another field, the ioctl size changes
which would render new user space running on that particular kernel to fail, because it
doesn't have the "just truncate the ioctl param to the size" logic yet.
You're right. So let's add the padding now, and only use the great new
stuff after it's actually in.
Working ugly is better than broken pretty.
