If syzbot is trying to test Tomoyo and this requires policy to be loaded, 
shouldn't it do that?

And again, I think the no-policy situation needs to be detected before 
you start trying to apply memory policies to running processes. Surely 
there is some much earlier point during initialization that you will 
detect that there is no policy?
