I've made a pull request (# 221) to the fio github, for logging and post-processing latency histograms.

Let me know what you think / try it out! -Karl Cronburg- -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
