   That being said, a number of people have asked that the networking hooks
   be able to "be compiled away", so we will be glad to do this.

That's the only big beef I have with the LSM stuff,
on a whole.

I want to be able to say CONFIG_SECURITY=n and all of
this stuff totally disappears.  So use macros that expand
to the security_ops->foo() when it's enabled, and compile
into do { } while (0) when it is disabled.

And yes, as much as the LSM folks may hate it, I want distribution
makes to be able to turn this stuff off at their discretion as well.

Some may decide that supporting a mechanism like this in their kernel
is just too much.
