I split up this patch into two separate patches: one for SLRU and one for the executor probes. I've done some documentation on the SLRU part, maybe you can look over it (to make sure i didn't break anything). I left the executor probes out of the documentation for now, since it seems not to be clear how they would manifest. Out of curiosity: Why do we want to pass the SlruCtl pointer down to the probes? I don't understand what those probes are going to do with those pointers, can you explain? -- Thanks Bernd
