Whilst cleaning up the dtrace probe documentation, I realized that there is nothing the aforementioned probes tell you that you can't find out (with a lot more data besides) from the final argument of the BUFFER_READ_DONE probe. Furthermore, tallying them as-is would be misleading since you couldn't distinguish true reads from relation extension requests. I think we should just remove them.
