Subject: + mm-damon-sysfs-schemes-rename-sysfs_filter-sz_range-to-range_minmax.patch added to mm-new branch
Date: Fri, 11 Sep 2026 16:19:38 -0700 [thread overview]
Message-ID: <20260911231939.1D9211F000FF@smtp.kernel.org> (raw)
The patch titled
Subject: mm/damon/sysfs-schemes: rename sysfs_filter->sz_range to range_{min,max}
has been added to the -mm mm-new branch. Its filename is
mm-damon-sysfs-schemes-rename-sysfs_filter-sz_range-to-range_minmax.patch
This patch will shortly appear at
https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-damon-sysfs-schemes-rename-sysfs_filter-sz_range-to-range_minmax.patch
This patch will later appear in the mm-new branch at
git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
Note, mm-new is a provisional staging ground for work-in-progress
patches, and acceptance into mm-new is a notification for others take
notice and to finish up reviews. Please do not hesitate to respond to
review feedback and post updated versions to replace or incrementally
fixup patches in mm-new.
The mm-new branch of mm.git is not included in linux-next
If a few days of testing in mm-new is successful, the patch will me moved
into mm.git's mm-unstable branch, which is included in linux-next
Before you just go and hit "reply", please:
a) Consider who else should be cc'ed
b) Prefer to cc a suitable mailing list as well
c) Ideally: find the original patch on the mailing list and do a
reply-to-all to that, adding suitable additional cc's
*** Remember to use Documentation/process/submit-checklist.rst when testing your code ***
The -mm tree is included into linux-next via various
branches at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
and is updated there most days

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.
