Very confused by the article. Is memoization new to the eBPF world? Did the author only just learn about it and wanted to use it?
In reality, the article is about correctly caching a path:policy mapping while working within the limitations of eBPF and Linux filesystem semantics. If you read the article in that context rather than wondering 'what is new and interesting about memoization in eBPF?' it's a lot more interesting.
I probably would have titled this 'Calculating cache keys for filesystem paths in eBPF' or something, since that's the cool and interesting problem that was solved.
Agent is an old school way to say "constantly running daemon to accomplish some specific purpose", as someone who wrote a lot of performance monitoring agents. AI is using the term appropriately, but I think assuming it's always AI-first is slightly tragic.
