Does this tool records results in a database keyed by kernel version/buildid for us to use it as a regression tool? Something that would produce results around these lines: "WARNING: test #23 counter #3 variance bigger than specified since the last kernel tested (git cset 55ed793afb4a8025d33a8e6a5f2f89d5ac4d8432)!" - Arnaldo - To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
