This was in response to being asked by a the maintainers of a bot that has wasted copious quanties of my time to please not waste their time. To prevent the wasting of time it was requested that when syzbot would be enabled on linux-next again that it only report issues when there is a reproducer, and it can narrow the issue down to at least the branch in linux-next the issue occured on. I thought there was general agreement on that point. That very much did not happen in this case. So I heard a request to not waste the time of a bot from people who have not taken what appear to be reasonable steps to not waste my time. I am especially annoyed that the bot despite having a reproducer was not able to at least narrow it down to the branch in linux-next. I was dismayed when I saw the syzbot report triggered someone to remove themselves from MAINTAINERS. Further I actually received a bug report (not found one by luck when I was skimming through a mailing list) from another group of people whose automated testing also found the issue and were able to succesfully root cause the issue. So I know good but reports are possible on this issue. In short. I have been burned by syzbot. I don't see evidence of change. I am grumpy. Eric
