Firstly V3 on github(never posted out) causes boot hang if CPU cores is >= 16, so you need to check if the test is still running, :-( Also V3 on github may not perform well on IB SRP(or other low latency SCSI disk), so I improve bio merge in V4 and make IB SRP's perf better too, and it depends on devices. I suggest to focus on V2 posted in mail list(V4 in github). -- Ming Lei
