I confused the effects from configuring user-limit-factor, minimum-user-limit-percent.

I understand that:

• minimum-user-limit-percent: a soft limit on the smallest amount of resources a single user should get access to if they are requesting it
• user-limit-factor: to control the max amount of resources that a single user can consume

It is acceptable to me when minimum-user-limit-percent * (1 / 100) <= user-limit-factor.

How is it going when user-limit-factor <= minimum-user-limit-percent * (1 / 100)? In this circumstance, I think user-limit-factor is only meaningful.
