From e386eed89c764f102fcc3c0d4c78c65a357f7399 Mon Sep 17 00:00:00 2001 From: Naoya Horiguchi Date: Tue, 5 May 2015 16:23:52 -0700 Subject: [PATCH] mm/hwpoison-inject: check PageLRU of hpage Hwpoison injector checks PageLRU of the raw target page to find out whether the page is an appropriate target, but current code now filters out thp tail pages, which prevents us from testing for such cases via this interface. So let's check hpage instead of p.
