Roman Gushchin began his session in the memory-management track of the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit by saying that the community has seen a lot of proposals adding BPF-based interfaces for memory management. None of them have made their way into the mainline, though. He wanted to explore the ways in which BPF might be helpful and the obstacles that have kept BPF-based solutions out so far. This session was followed by a discussion led by Shakeel Butt on what the requirements for a new, BPF-based interface for memory control groups might look like.
