So, I thought it would be good to keep the >maintainer info updated in the older stable kernels too. If you look at cases like these, I can see an argument around bringing it back to -stable. However, changes in the upstream MAINTAINERS file aren't limited to just change in maintainers. How would we handle addition of maintainers of a new code upstream? Or removal of maintainers due to code deletion? Or code movement upstream that isn't reflected in the stable tree (think a driver graduating from staging). It becomes a mess quite quickly and the easiest solution here is to just use upstream's MAINTAINERS file. Maybe we should just remove MAINTAINERS from stable trees to make it obvious. -- Thanks, Sasha _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
