You mean by adding additional checks within the body of an ioctl=20
somewhere, on top of the simple flags where the ioctl is initially declar=
ed?

I don't see that it is a particular problem to do this.  Eg. you could=20
allow the X server access to some commands in the via_verifier which=20
aren't available to regular clients.  I think that sort of usage would=20
make a lot of sense.
