+Subject: [PATCH] Authorize MachinePool Operations
+
+https://github.com/kubernetes/autoscaler/pull/4676 Introduced a bug where the autoscaler runtime fails to reconcile other CAPI machine resources when its ClusterRole is not authorized to list and watch MachinePool resources.
+
+See: https://github.com/kubernetes/autoscaler/commit/17d2bd968e756d97598be3ffb333957f0cfe99bf#diff-c8813a0942bbcd464aaa04a04c2c71897d5df30b65a2db86cb81773016f24406R786
+
+To resolve this issue, we authorize appropriate operations on MachinePool resources.
