Deadlocks are a constant threat in concurrent settings with shared data; it is thus not surprising that the kernel project has long since developed tools to detect potential deadlocks so they can be fixed before they affect production users. Byungchul Park thinks that he has developed a better tool that can detect more deadlock-prone situations. At the 2025 Open Source Summit Europe, he presented an introduction to his dependency tracker (or "DEPT") tool and the kinds of problems it can detect.
