Its filename was mm-damon-sysfs-remove-duplicated-commit-input-validity-check.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: remove duplicated commit input validity check Date: Sun, 5 Jul 2026 08:55:54 -0700 DAMON sysfs interface does parameters validation-purpose damon_commit_ctx() calls for parameters update. Now the same logic is embedded inside damon_commit_ctx() itself. Hence, the validation in DAMON sysfs interface is just an unnecessary duplicate. Remove it.
