+Subject: [PATCH] Add secure_modules() call
+
+Provide a single call to allow kernel code to determine whether the system
+has been configured to either disable module loading entirely or to load
+only modules signed with a trusted key.
+
+Bugzilla: N/A
+Upstream-status: Fedora mustard.  Replaced by securelevels, but that was nak'd
+
