Hello, this is the second iteration of my patches for flexible proportions. Since previous submission, I've converted BDI proportion calculations to use flexible proportions so now we can test proportions in kernel. Fengguang, can you give them a run in your JBOD setup? You might try to tweak VM_COMPLETIONS_PERIOD_LEN if things are fluctuating too much... I'm not yet completely decided how to set that constant. Thanks!
