Rusty Russell <rusty@rustcorp.com.au> writes:

FWIW i had something similar using the gcc union extension at some
point for ioctls because I was tired for all the ugly casts from
unsigned long arg to void * in ioctl handlers.

But I decided to not push it because sparse would have likely choked 
on it, and sparse actually finds a lot of bugs so it's more important than
having a few more casts.
