In March 2025, Bhushan Shah focused on improving the reliability of the input subsystem in the canonical/mir repository by addressing a persistent issue in the evdev device watcher cleanup path. Using C++ and leveraging expertise in device drivers and embedded Linux kernel development, Bhushan implemented a targeted bug fix that ensures device watchers are properly removed when devices are detached. This approach uses device numbers for accurate identification, preventing stale watchers and enabling reliable device re-attachment in multi-device environments. The work resulted in clearer, more maintainable code, reducing support overhead and improving runtime stability for systems relying on evdev input handling.
