In the current code, we begin to report pressure soon after the balloon driver loads and typically report a very low pressure until the system is fully operational. To avoid having the host take memory balancing decisions on data that does not fully reflect the memory pressure, delay reporting the pressure. Additionally, implement a floor for ballooning based on the amount of memory being managed. K. Y.
