I guess they needs I think patches like this needs to be landed like: This brakeage is too early. Leaving bots broken for a long time will likely hide other regression, which make hard for bot maintainers to pinpoint the cause. |

The only two bots I still see failing are: I already fixed the first one on llvm-zorg, and I can't find where the second one is defined, but the bot owner is aware of the problem. @vitalybuka Is there still a need to revert this? |
