* The structure argument to _IOW() is used to add a structure size component

* on Digital Unix, where user space code is compiled in 64-bit mode.
*
* So, in kernel space, regardless whether it is compiled in 32-bit mode or
* 64-bit mode, the kernel code can use the struct ViceIoctl32 version of
* _IOW() to check the size of user space arguments -- except on Digital Unix
* (or Linux on Alpha, since it's compatible with Digital Unix). We don't
* care about other 64-bit Linux versions since they don't check this length.
