Its filename was mm-memory-failure-not-select-memory_isolation.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Xie Yuanbin Subject: mm/memory-failure: don't select MEMORY_ISOLATION Date: Mon, 22 Sep 2025 22:36:18 +0800 We added that "select MEMORY_ISOLATION" in commit ee6f509c3274 ("mm: factor out memory isolate functions"). However, in commit add05cecef80 ("mm: soft-offline: don't free target page in successful page migration") we remove the need for it, where we removed the calls to set_migratetype_isolate() etc. What CONFIG_MEMORY_FAILURE soft-offline support wants is migrate_pages() support. But that comes with CONFIG_MIGRATION. And isolate_folio_to_list() has nothing to do with CONFIG_MEMORY_ISOLATION. Therefore, we can remove "select MEMORY_ISOLATION" of MEMORY_FAILURE.
