From 679e46c04049f8e753e5d3467a819a5f92c6fcb7 Mon Sep 17 00:00:00 2001 From: Viktor Rosendahl Date: Thu, 11 Sep 2008 19:20:39 +0300 Subject: [PATCH] lowmem: Security modules can no longer be removed. The unregister_security() and mod_unreg_security() functions were removed because the upstream developers believe that it should not be possible to remove security modules, "It is used only by out-of-tree modules, which are often binary-only, illegal, abusive of the API and dangerous, e.g. silently re-vectoring SELinux."
