The quilt patch titled

has been removed from the -mm tree. Its filename was
samples-damon-prcl-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

Subject: samples/damon/prcl: avoid starting DAMON before initialization
Date: Mon, 8 Sep 2025 19:22:37 -0700
Commit 2780505ec2b4 ("samples/damon/prcl: fix boot time enable crash") 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.
