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.
