Subject: [PATCH] mm: Fix compile error due to COMPACTION_HPAGE_ORDER
Date: Mon, 22 Jun 2020 23:45:44 -0700 [thread overview]
Message-ID: <20200623064544.25766-1-nigupta@nvidia.com> (raw)
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.
