Its filename was mm-damon-sysfs-schemes-use-damon_nr_accesses_mvsum-for-damo-regions.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-schemes: use damon_nr_accesses_mvsum() for damo regions Date: Mon, 29 Jun 2026 21:08:00 -0700 damon_nr_accesses_mvsum() returns a value same to nr_accesses_bp. Also the function is more simple and therefore more tolerant to errors. Execution of the function would be more expensive than the simple read of the field, but because the function is quite simple, the overhead should be negligible. Use it in the DAMON sysfs interface for scheme-tried regions, instead of the nr_accesses_bp.
