   6           Any files read through the kernel file reading interface
   7           (kernel modules, firmware, kexec images, security policy)
   8           can be pinned to the first filesystem used for loading. When
   9           enabled, any files that come from other filesystems will be
  10           rejected. This is best used on systems without an initrd that
  11           have a root filesystem backed by a read-only device such as
  12           dm-verity or a CDROM.

  18           If selected, LoadPin will enforce pinning at boot. If not
  19           selected, it can be enabled at boot with the kernel parameter
  20           "loadpin.enforce=1".
