[merged mm-stable] mm-damon-sysfs-schemes-use-switch-case-in-add_scheme_filters.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm/damon/sysfs-schemes: use switch-case in add_scheme_filters()
has been removed from the -mm tree.  Its filename was
     mm-damon-sysfs-schemes-use-switch-case-in-add_scheme_filters.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: use switch-case in add_scheme_filters()
Date: Mon, 14 Sep 2026 07:23:23 -0700

damon_sysfs_add_scheeme_filters() has long if-else chains for DAMOS filter
types.  Convert the code to use switch-case, which would be cleaner and
more efficient.
