Its filename was mm-mglru-restrict-eviction-accounting-to-eligible-zones.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: "Barry Song (Xiaomi)" Subject: mm/mglru: restrict eviction accounting to eligible zones Date: Thu, 12 Nov 2026 07:25:59 +0800 For both lruvec_evictable_size() and lru_gen_imbalanced(), only count eligible zones below sc->reclaim_idx. This avoids inflating the number of scanned pages and allows aging to proceed more promptly when eligible zones have few folios.
