[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled
     Subject: mm/damon/core: s/damon_max_nr_accesses()/damon_nr_samples_per_aggr()/
has been removed from the -mm tree.  Its filename was
     mm-damon-core-s-damon_max_nr_accesses-damon_nr_samples_per_aggr.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/core: s/damon_max_nr_accesses()/damon_nr_samples_per_aggr()/
Date: Wed, 8 Jul 2026 06:53:52 -0700

damon_max_nr_accesses() actually returns the number of samples DAMON
checks for each region per each aggregation interval.  Rename it to better
describe what it really does and not confusing for more general uses.
