The devices can be created at run-time for quite some time already and the

This is pretty much the same situation as was with the block loop devices
which was solved by adding a build-time configuration that the
distributions could use as they deem fit while keeping the default for
compatibility.

Let's do that here as well.

There is already a module parameter for this, so making it a compile
time option adds nothing.
