The multi-generational LRU (MGLRU) is an alternative memory-management algorithm that was merged for the 6.1 kernel in late 2022. It brought a promise of much-improved performance and simplified code. Since then, though, progress on MGLRU has stalled, and it still is not enabled on many systems. As the 2026 Linux Storage, Filesystem, Memory-Management and BPF Summit (LSFMM+BPF) approaches, several memory-management developers have indicated a desire to talk about the future of MGLRU. While some developers are looking for ways to improve the subsystem, another has called for it to be removed entirely.
