From 504c1cabe325df65c18ef38365ddd1a41c6b591b Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Tue, 25 Jan 2022 21:22:21 +0800 Subject: mm/balloon_compaction: make balloon page compaction callbacks static Since commit b1123ea6d3b3 ("mm: balloon: use general non-lru movable page feature"), these functions are called via balloon_aops callbacks. They're not called directly outside this file. So make them static and clean up the relevant code.
