ioctls with a variable argument length are a pain for 32 bit
emulation and stuff like strace. You either need to encode
the variable length into the ioctl cmd, making it variable
as well, or use a pointer in the data structure, which requires
conversion.
Ideally, ioctl arguments have a constant layout, no pointers
and are at most 64 bits long.
