+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.
