The quilt patch titled
Subject: mm/damon/sysfs-schemes: rename sysfs_filter->sz_range to range_{min,max}
has been removed from the -mm tree. Its filename was
mm-damon-sysfs-schemes-rename-sysfs_filter-sz_range-to-range_minmax.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

Subject: mm/damon/sysfs-schemes: rename sysfs_filter->sz_range to range_{min,max}
Date: Fri, 11 Sep 2026 06:55:06 -0700
DAMON sysfs interface provides 'min' and 'max' files under the DAMOS
filter directory. The purpose is setting the general range arguments for
hugepage_size like filters that require range arguments. So far,
hugepage_size was the only filter using it. Hence sz_range field of
damon_sysfs_scheme_filter struct was connected to the files.
In future, we could add a new filter that can reuse the 'min' and 'max'
files. And the filter might use a range of a type that is not size. For
example, probe_hits weighted sum. In this case, simply reusing the
sz_range field would make it a little confusing. Rename sz_range to
range_{min,max} to avoid such confusion.
