SELinux: allow userspace to read policy back out of the kernel
There is interest in being able to see what the actual policy is that was loaded into the kernel. The patch creates a new selinuxfs file /selinux/policy which can be read by userspace. The actual policy that is loaded into the kernel will be written back out to userspace. Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: James Morris <jmorris@namei.org>
