[Andrew Morton]

The quilt patch titled
     Subject: mm/damon/core: commit hugepage_size type damon filter
has been removed from the -mm tree.  Its filename was
     mm-damon-core-commit-hugepage_size-type-damon-filter.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 <sj@kernel.org>
Subject: mm/damon/core: commit hugepage_size type damon filter
Date: Tue, 15 Sep 2026 07:33:51 -0700

Extend data attribute probe filters commit logic for the new hugepage_size
filter type.  Since it needs to carry the size range of the hugepage,
update the logic to update the size range fields of the commit destination
filter struct.  While doing that, validate the given range and propagate
an error if it is invalid.  Add the error handling in the callers, too.
