Its filename was mm-damon-ops-common-factor-out-damon_putback_folio_list.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: Li Youhong Subject: mm/damon/ops-common: factor out damon_putback_folio_list() Date: Mon, 31 Aug 2026 07:26:05 -0700 The putback loop is duplicated in damon_migrate_folio_list() and on the invalid-nid path of damon_migrate_pages(). Factor it into a small helper for readability. No functional change.
