Limits: The demonstrated domain is prefetching; eBPF verifier and helper interfaces bound policy expressiveness. FetchBPF exposes memory-prefetch hooks and policy state through eBPF, enabling verified user-defined policies in a stock-kernel framework. S3ResearchAgent medium Venue: USENIX ATC. Year: 2024. Kernel-resident prefetch policies are hard to prototype, deploy, and tailor per workload.

Question: Can Linux memory-prefetch policies be customized safely without maintaining kernel forks? Context: Kernel-resident prefetch policies are hard to prototype, deploy, and tailor per workload.

Evaluation: workloads=prefetch policies reproduced from prior work; baselines=equivalent native-kernel policies; metrics=runtime overhead; prefetch effectiveness; results=negligible framework overhead Interpretation: A constrained programmable interface can preserve performance while shortening policy iteration and deployment. Reusable lesson: Move policy into a safe extension layer while keeping mechanisms in the kernel. Applicability: Linux VM prefetch experimentation and workload-specific deployment.
