From a6c5e0f75b3f7b8ace146f4eaa6398774d39a640 Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Thu, 25 Feb 2021 17:18:34 -0800 Subject: [PATCH] mm/zsmalloc.c: use page_private() to access page->private It's recommended to use helper macro page_private() to access the private field of page. Use such helper to eliminate direct access.
