+ * VRUNTIME
+ * ========
+ *
+ * COROLLARY #1: The virtual runtime of the entity needs to be
+ * adjusted if re-weight at !0-lag point.
+ *
+ * Proof: For contradiction assume this is not true, so we can
+ * re-weight without changing vruntime at !0-lag point.
+ *
+ * Weight VRuntime Avg-VRuntime
+ * before w v V
+ * after w' v' V'
+ *
+ * Since lag needs to be preserved through re-weight:
+ *
+ * lag = (V - v)*w = (V'- v')*w', where v = v'
+ * ==> V' = (V - v)*w/w' + v (1)
+ *
+ * Let W be the total weight of the entities before reweight,
+ * since V' is the new weighted average of entities:
+ *
+ * V' = (WV + w'v - wv) / (W + w' - w) (2)
+ *
+ * by using (1) & (2) we obtain:
+ *
+ * (WV + w'v - wv) / (W + w' - w) = (V - v)*w/w' + v
+ * ==> (WV-Wv+Wv+w'v-wv)/(W+w'-w) = (V - v)*w/w' + v
+ * ==> (WV - Wv)/(W + w' - w) + v = (V - v)*w/w' + v
+ * ==> (V - v)*W/(W + w' - w) = (V - v)*w/w' (3)
+ *
+ * Since we are doing at !0-lag point which means V != v, we
+ * can simplify (3):
+ *
+ * ==> W / (W + w' - w) = w / w'
+ * ==> Ww' = Ww + ww' - ww
+ * ==> W * (w' - w) = w * (w' - w)
+ * ==> W = w (re-weight indicates w' != w)
+ *
+ * So the cfs_rq contains only one entity, hence vruntime of
+ * the entity @v should always equal to the cfs_rq's weighted
+ * average vruntime @V, which means we will always re-weight
+ * at 0-lag point, thus breach assumption. Proof completed.
+ *
+ *
+ * COROLLARY #2: Re-weight does NOT affect weighted average
+ * vruntime of all the entities.
+ *
+ * Proof: According to corollary #1, Eq. (1) should be:
+ *
+ * (V - v)*w = (V' - v')*w'
+ * ==> v' = V' - (V - v)*w/w' (4)
+ *
+ * According to the weighted average formula, we have:
+ *
+ * V' = (WV - wv + w'v') / (W - w + w')
+ * = (WV - wv + w'(V' - (V - v)w/w')) / (W - w + w')
+ * = (WV - wv + w'V' - Vw + wv) / (W - w + w')
+ * = (WV + w'V' - Vw) / (W - w + w')
+ *
+ * ==> V'*(W - w + w') = WV + w'V' - Vw
+ * ==> V' * (W - w) = (W - w) * V (5)
+ *
+ * If the entity is the only one in the cfs_rq, then reweight
+ * always occurs at 0-lag point, so V won't change. Or else
+ * there are other entities, hence W != w, then Eq. (5) turns
+ * into V' = V. So V won't change in either case, proof done.
+ *
+ *
+ * So according to corollary #1 & #2, the effect of re-weight
+ * on vruntime should be:
+ *
+ * v' = V' - (V - v) * w / w' (4)
+ * = V - (V - v) * w / w'
+ * = V - vl * w / w'
+ * = V - vl'
