From e9891bd0c1f2279b51bc3202ff6c741d68a7c534 Mon Sep 17 00:00:00 2001 From: Ye Liu Date: Thu, 14 Aug 2025 15:18:28 +0800 Subject: [PATCH] mm/page_alloc: remove redundant pcp->free_count initialization in per_cpu_pages_init() In per_cpu_pages_init(), pcp->free_count is explicitly initialized to 0, but this is redundant because the entire struct is already zeroed by memset(pcp, 0, sizeof(*pcp)).
