yes, there is a note in metaclick explaining how to check. But it's not complete, neither is werner's site: you check for those counters in /proc/slabinfo being non-zero *AND* changing in value when you startup Oracle! There might be *other* software around already using aio and just having them as non-zero is not enough to say Oracle is using it.
