Subject: [PATCH] device/main/linux-postmarketos-allwinner: Enabe LRU_GEN by
 default (MR 3686)

MGLRU seeks to address Linux's poor page reclamation behavior with this new high performance LRU implementation to over-commit memory.
MGLRU has shown to be beneficial in a variety of benchmarks especially on memory constrained systems.

Some benchmarks:
