The Linux ecosystem—spanning upstream mainline, stable and LTS branches, and downstream distributions like Ubuntu and Android—relies on patch porting to ensure stability and security. However, concerns persist about delayed or incomplete patch propagation. By mining software repositories across 28 Linux branches (e.g., Android,Ubuntu,Debian,OpenSLE and etc) and 584K patches., we uncover diverse patch porting strategies and their trade-offs, measured through patch delay, patch rate, and bug inheritance ratio. We also analyze the factors influcing the patch porting practices and offer actionable insights to enhance patch flow efficiency and strengthen the Linux ecosystem.
