Its filename was samples-damon-prcl-use-damon_initialized.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: SeongJae Park Subject: samples/damon/prcl: use damon_initialized() Date: Mon, 15 Sep 2025 20:35:10 -0700 damon_sample_prcl is assuming DAMON is ready to use in module_init time, and uses its own hack to see if it is the time. Use damon_initialized(), which is a way for seeing if DAMON is ready to be used that is more reliable and better to maintain instead of the hack.
