It is false positive: "this bug is not introduced by me!" However if you take a broader view, it's still notifying the possibly "relevant" people who may know the background about that bug, or whom to further CC the report. :) Thanks, Fengguang ^ permalink raw reply [flat|nested] 3+ messages in thread

No apology required. I think we all appreciate the build test coverage, and I saw your mail where you said you sent out ~60 reports yesterday- wow!

I think we all appreciate the build test > coverage, and I saw your mail where you said you sent out ~60 > reports yesterday- wow! Paul, thank you! But let me clarify it a bit. The kernel test robots typically send out 30+ reports per day, including build/boot error/warnings, performance/power/functional regressions, and build test completion notifications. The ~60 emails I mentioned are the ones that I write up in mutt, most of them are on internal development and maintenance works of the test infrastructure.
