| Description | In poolamc.c, there's a PageRetStruct which is used to accumulate statistics about pages condemned, reclaimed and retained. This is unused, untested and obsolete (it talks about "pages" when it should talk about "arena grains" [1]). |
| Analysis | This structure was added by Richard Kistruck in change 168562 [2] when he was trying to improve collection speed in the presence of large objects (job002205). The same information could better be collected via the telemetry system, by adding AMCWhiten and AMCReclaim events. |
| How found | inspection |
