Hi Christophe and Guan, I was hoping to get down to the review before Christophe committed your your patch "calculate standard deviation on a logarithmic scale for prioritizer path_latency". I failed to do this in timely manner, sorry. But I still have some issues with the patch. Please check these fixes. I also have remaining issues with the "intermittent IO accounting" patch, will send these later.
