Urk, no.
This will result in older applications picking up the new ioctl when
they are rebuilt without having explicit support for the new ioctl.
Just create a new ioctl with a new name and modify applications to
use it. If the kernel does not support the new ioctl, then fall back
to the old one in userspace.
