From: Ye Liu Date: Thu, 14 Aug 2025 07:18:28 +0000 (+0800) Subject: mm/page_alloc: remove redundant pcp->free_count initialization in per_cpu_pages_init() X-Git-Tag: v6.18-rc1~130^2~290 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=5922deb3ecc0e3c6027e4779e00d2505ebeba9df;p=thirdparty%2Fkernel%2Flinux.git 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)).
