commit 7d4776545b0f8a8827e5d061206faf61c9ba6ea9 Author: Patrick Delaunay patrick.delaunay@st.com Date: Thu Apr 18 17:32:49 2019 +0200
env: solve compilation error in SPLLooking into the history of this, I wonder if we could / should have prevented this.
As far as I can see, Patrick's patch series has not been reviewed by others, probably because general intetest in STM32 is not that big at the moment. I can see no Acked-by:, Reviewed-by: nor Tested-by: tags - nothing.
The whole patch series was then pulled from the u-boot-stm repository.
However, there was not only STM related code in there. There were changes to common code like the environment handling. common code was changed without review and without testing.
It seems this should be unacceptable even if it's in the area of interest. Isn't an Acked-by generally accepted as required?
Are there ways to prevent this?
Yes, we can appeal to the custodians to be more careful, but I assume they are already doing their best.
It seems the diffstat should be a quick way to see this, so I would think not quite their best. Maybe a reminder / recommendation that it be reviewed by custodians?
It might have even been better if this had been a sub-system with a clear maintainer, but there is no such person for the environment code.
How can we prevent this in the future?
Is there any tooling around the MAINTAINERS file that can be used to reg-flag PRs that contain changes outside of the tree's area of effect?
Should we define "interested developers" for such areas that have no custodian (the "Designated reviewer") entry in the MAINTAINERS file could be used for this, for example)?
I like that idea, though in this specific case I think there should be a maintainer for env.
Better ideas?
Best regards,
Wolfgang Denk
