Maintaining a 100% correct stable-like tree is nearly impossible; all it takes is one mistake to cause critical bugs for users who require the highest stability. Given the amount of patches that flow through mainline, it is nearly impossible to construct a correct stable tree. A significant amount of work maintaining these trees is being done manually, leaving more room for mistakes that are missed because the existing automatic testing tools lack the intelligence to handle the attributes of stable trees. This presentation will introduce the stable-maintainer tools. A set of scripts used to automate the process of creation a tree and validating it's correctness. The tools are able to detect extraneous or missing commits, incorrectly backported commits, and invalid dependency Chains.
