But just doing default things does not seem to find much. I guess
common paths through the hooks are well exercised already.
So perhaps if we do more non-trivial things, it can find more stuff.
But what are they? Adding/changing/removing xattr's? Which? What are
the values? Changing security contexts? How? What else?
selinux has own filesystem and we should touch some files there:
https://github.com/google/syzkaller/blob/master/sys/linux/selinux.txt
But we don't anything similar for other modules.
