Its filename was mm-damon-sysfs-move-unsigned-long-range-directory-to-common-module.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: SeongJae Park Subject: mm/damon/sysfs: move unsigned long range directory to common module Date: Wed, 26 Oct 2022 22:59:39 +0000 The implementation of unsigned long type range directories can be reused by multiple DAMON sysfs directories including those for DAMON-based Operation Schemes and the range of number of monitoring regions. Move the code into the files for DAMON sysfs common logics.
