The quilt patch titled
     Subject: mm: make show_free_areas() static
has been removed from the -mm tree.  Its filename was
     mm-make-show_free_areas-static.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: make show_free_areas() static
Date: Fri, 30 Jun 2023 14:22:53 +0800

All callers of show_free_areas() pass 0 and NULL, so we can directly use
show_mem() instead of show_free_areas(0, NULL), which could make
show_free_areas() a static function.
