How are you using this SELinux information in the kernel and/or in
userspace? What's the purpose of it? What are you comparing it
against? Why do you care if it changes?

Note btw that the notion of a policy name/type and the policy file path
is purely a userspace construct and shouldn't be embedded in your
kernel code. Android for example doesn't follow that convention at
all; their SELinux policy file is simply /sepolicy. On modern kernels,
you can always read the currently loaded policy from the kernel itself
via /sys/fs/selinux/policy (formerly just /selinux/policy).
