+What:   USER_SCHED
+When:   2.6.34
+
+Why:    USER_SCHED was implemented as a proof of concept for group scheduling.
+        The effect of USER_SCHED can already be achieved from userspace with
+        the help of libcgroup. The removal of USER_SCHED will also simplify
+        the scheduler code with the removal of one major ifdef. There are also
+        issues USER_SCHED has with USER_NS. A decision was taken not to fix
+        those and instead remove USER_SCHED. Also new group scheduling
+        features will not be implemented for USER_SCHED.
