Packs prefetch-staging and prefetch-staging-purge counts for sixteen open volumes per table row, covering prefetch activity driven by both host reads and copy operations combined (unlike the split host-only/copy-only counters elsewhere). Admins use the purge count here to judge overall prefetch efficiency across all I/O sources for a given volume.
