During March 2026, Mhmrdd focused on improving kernel process marking reliability in the KernelSU repository. Working in C and leveraging kernel development expertise, Mhmrdd addressed edge cases that could destabilize process lifecycles in built-in mode, particularly for containerized workloads. The work involved hardening the logic to ensure that pid 1 is always marked before transitioning to init and preventing unmarking when the execution path is unreadable, thereby reducing the risk of incorrect process states. The targeted fix demonstrated careful attention to stability and correctness, with clear commit messaging and minimal code changes that aligned with project standards and test coverage.
