It had a clean abstracted API to allow it to be used by systems outside of tracing. The API even allowed the ring buffer code to be drastically changed without affecting the tracing sub-system. Recently, Vincent Donnefort has been contributing a lot of work to enhance the ring buffer. He implemented the user space mappings and recently created a version to allow pKVM hypervisors to use the code to trace the hypervisor and expose the events to the user. Create a separate category for maintaining the ring buffer code so that Vincent can become an official maintainer of it. His work has little to do with the tracing code itself. In the future, he may even be the main maintainer of the ring buffer.
