[$] What is to be done about MGLRU?

"Reclaim" is the task of finding memory that can be taken away from itscurrent user and put to better uses within the system; it is a core part ofthe memory-management picture. The addition of the multi-generational LRU (MGLRU) was meant toprovide a better reclaim implementation than the "traditional LRU" thatpreceded it, but MGLRU has complicated the situation instead. No fewer thanthree memory-management-track sessions at the 2026 Linux Storage,Filesystem, Memory Management, and BPF Summit were focused on MGLRU,with an eye toward integrating it more fully, improving its performance,and addressing some problems encountered with Android systems.
