From d84da3f9e4f18809821562bd960e00a10673b341 Mon Sep 17 00:00:00 2001 From: "Kirill A. Shutemov" Date: Tue, 11 Dec 2012 16:00:31 -0800 Subject: [PATCH] mm: use IS_ENABLED(CONFIG_COMPACTION) instead of COMPACTION_BUILD We don't need custom COMPACTION_BUILD anymore, since we have handy IS_ENABLED().
