Worked on the ctrliq/kernel-src-tree repository to enhance CI automation by updating GitHub Actions workflows. Focused on synchronizing additional branches, the developer modified the sync.yml configuration to include both stable_6.12.y and centos9 branches, ensuring these tracked upstream kernel changes in parallel with existing branches. This approach improved multi-branch parity and streamlined the CI/CD process, allowing for more consistent integration and testing across multiple kernel versions. The work was implemented using YAML for workflow definitions and leveraged GitHub Actions as the automation platform. No major bugs were addressed during this period, with efforts concentrated on feature delivery and workflow reliability.
