But he's not actually doing PERF_RECORD_UNMAP, nor is his perf_munmap() hook sufficient to actually generate those. Now I agree that if he's going to do an munmap hook, he should do it 'right' and at the very least allow for PERF_RECORD_UNMAP to be done, but ideally simply pick up and finish that patch we had back then.
