Subject: [PATCH 0/4] LoadPin: Allow filesystem switch when not enforcing

Hi,

Right now, LoadPin isn't much use on general purpose distros since modules
tend to be loaded from multiple filesystems at boot (first initramfs,
then real rootfs). Allow the potential mount pin to move when enforcement
is not enabled.
