If anyone has any objections, please let me know. ------------------ From: Joonsoo Kim commit dc32f63453f56d07a1073a697dcd843dd3098c09 upstream. Commit a6bc32b89922 ("mm: compaction: introduce sync-light migration for use by compaction") changed the declaration of migrate_pages() and migrate_huge_pages(). But it missed changing the argument of migrate_huge_pages() in soft_offline_huge_page(). In this case, we should call migrate_huge_pages() with MIGRATE_SYNC. Additionally, there is a mismatch between type the of argument and the function declaration for migrate_pages().
