Its filename was mm-damon-sysfs-pass-preps-to-damon-core.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/sysfs: pass preps to DAMON core Date: Tue, 1 Sep 2026 06:25:00 -0700 DAMON sysfs interface provides the files for setting DAMON probe preps. But the underlying code is not really passing the user-set values to DAMON core. Pass those.
