LearnedCache: An eBPF-Integrated Perceptron-Based Eviction Policy for the Linux Page Cache

arXiv:2605.26168v1 Announce Type: cross Abstract: Linux is the foundation of the digital age, accounting for the majority of the cloud and mobile OS markets. Any device that runs Linux uses the Linux page cache, a central pillar in OS and application performance, serving to reduce extraneous disk access. Many page cache eviction policies have been developed but remain bound by the rigidity of heuristics. The rise of AI-driven tools in recent years, melded with the ever-increasing variety of workloads for Linux devices, sets the stage for machine-learning-driven cache eviction policies. Promisi

Why this matters
Why now

The increasing complexity and variety of workloads for Linux devices, coupled with advancements in AI, make machine-learning-driven cache eviction policies both necessary and feasible.

Why it’s important

Improving the fundamental performance of the Linux page cache, which underpins the majority of cloud and mobile OS markets, has widespread implications for computing efficiency and resource utilization.

What changes

Traditional heuristic-based cache eviction policies in Linux systems can now be augmented or replaced by adaptive, AI-driven approaches, potentially leading to more efficient resource management.
