Summary
Ingested excerpt (first ~500 chars of normalized text).

During a memory-management-track session at the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit , Yang Shi proposed a fundamental, and somewhat controversial, change to how these operations work in order to provide better performance on a wider range of architectures.
