From 25788738eb9ce46fe6a0fd84a3ceef5c795d41f0 Mon Sep 17 00:00:00 2001 From: Nitin Gupta Date: Tue, 11 Aug 2020 18:31:04 -0700 Subject: mm: fix compile error due to COMPACTION_HPAGE_ORDER Fix compile error when COMPACTION_HPAGE_ORDER is assigned to HUGETLB_PAGE_ORDER. The correct way to check if this constant is defined is to check for CONFIG_HUGETLBFS.
