I thought what you meant is that we would carry a special API deviation in the architecture code or expose the sh_pmu structure to generic code, both of which I have no interest in. My preferred solution is that we provide a perf_pmu_name() in the generic perf code as a __weak and then override it in the sh code, where we have sh_pmu visibility. This way we aren't providing any special APIs and sh_pmu remains constrained to the sh perf events code. -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
