Its filename was mm-damon-paddr-support-damon_prep.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: SJ Park Subject: mm/damon/paddr: support damon_prep Date: Tue, 1 Sep 2026 06:24:55 -0700 Implement damon_operations->prep_probes() callback. Support the only existing prep action, DAMON_PREP_SET_PGIDLE in a way similar to what it was doing for the access check preparation: unset page table accessed bits and set PG_Idle flag. Reuse the function for the access check preparation.
