Subject: [PATCH] mm/gup: Add folio to list when folio_isolate_lru() succeed
Date: Tue, 31 Jan 2023 14:32:06 +0800	[thread overview]
Message-ID: <20230131063206.28820-1-Kuan-Ying.Lee@mediatek.com> (raw)

If we call folio_isolate_lru() successfully, we will get
return value 0. We need to add this folio to the
movable_pages_list.

Fixes: 67e139b02d99 ("mm/gup.c: refactor check_and_migrate_movable_pages()")
