Oh sorry.   As long as we do the whole rcu protected thing so it is safe
to call the function without taking locks it should work.  I'm not
thrilled about a function pointer but it should work.

Depending.  It doesn't sound like svm has the problem where init doesn't
work so svm really doesn't need to do this.
