+Automatic feedback-driven quota tuning. Instead of setting the absolute quota
+value, users can repeatedly provide numbers representing how much of their goal
+for the scheme is achieved as feedback. DAMOS then automatically tunes the
+aggressiveness (the quota) of the corresponding scheme. For example, if DAMOS
+is under achieving the goal, DAMOS automatically increases the quota. If DAMOS
+is over achieving the goal, it decreases the quota.
