+config SECURITY_LOADPIN
+        bool "Pin load of kernel files (modules, fw, etc) to one filesystem"
+        depends on SECURITY && BLOCK
+        help
+          Any files read through the kernel file reading interface
+          (kernel modules, firmware, kexec images, security policy) will
+          be pinned to the first filesystem used for loading. Any files
+          that come from other filesystems will be rejected. This is best
+          used on systems without an initrd that have a root filesystem
+          backed by a read-only device such as dm-verity or a CDROM.
