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

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