Subject: [PATCH] mm/memory-failure: Fix return wrong value when isolate page fail
Date: Sun, 30 Aug 2020 16:10:53 +0800 [thread overview]
Message-ID: <20200830081053.64981-1-songmuchun@bytedance.com> (raw)
When we isolate page fail, we should not return 0, because we do not
set page HWPoison on any page.
