Its filename was mm-damon-core-use-abs_diff-in-damon_feed_loop_next_input.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/core: use abs_diff() in damon_feed_loop_next_input() Date: Thu, 17 Sep 2026 07:22:00 -0700 damon_feed_loop_next_input() is open-coding absolute diff calculation instead of the dedicated helper, abs_diff(), for no good reason. Use the dedicated helper.
