[Andrew Morton]

The quilt patch titled
     Subject: mm/damon/core: introduce damon_probe_hits_mvsum()
has been removed from the -mm tree.  Its filename was
     mm-damon-core-introduce-damon_probe_hits_mvsum.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: introduce damon_probe_hits_mvsum()
Date: Fri, 3 Jul 2026 10:06:02 -0700

Implement a function for getting a reasonable best effort quality pseudo
moving sums of probe_hits on demands.  It reuses the internal function for
the pseudo moving sum for data access frequency (nr_accesses).
