Its filename was samples-damon-mtier-avoid-starting-damon-before-initialization.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: SeongJae Park Subject: samples/damon/mtier: avoid starting DAMON before initialization Date: Mon, 8 Sep 2025 19:22:38 -0700 Commit 964314344eab ("samples/damon/mtier: support boot time enable setup") is somehow incompletely applying the origin patch [1]. It is missing the part that avoids starting DAMON before module initialization. Probably a mistake during a merge has happened. Fix it by applying the missed part again.
