@@ -315,3 +315,15 @@ When:	2.6.29 (ideally) or 2.6.30 (more likely)
 Why:	Deprecated by the new (standard) device driver binding model. Use
 	i2c_driver->probe() and ->remove() instead.
 Who:	Jean Delvare <khali@linux-fr.org>
+
+---------------------------
+
+What:	SELinux "compat_net" functionality
+When:	2.6.30 at the earliest
+Why:	In 2.6.18 the Secmark concept was introduced to replace the "compat_net"
+	network access control functionality of SELinux.  Secmark offers both
+	better performance and greater flexibility than the "compat_net"
+	mechanism.  Now that the major Linux distributions have moved to
+	Secmark, it is time to deprecate the older mechanism and start the
+	process of removing the old code.
+Who:	Paul Moore <paul.moore@hp.com>
