[Andrew Morton]

The quilt patch titled
     Subject: mm/rmap: make anon_vma functions internal
has been removed from the -mm tree.  Its filename was

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/rmap: make anon_vma functions internal
Date: Sun, 18 Jan 2026 14:50:42 +0000

The bulk of the anon_vma operations are only used by mm, so formalise this
by putting the function prototypes and inlines in mm/internal.h.  This
allows us to make changes without having to worry about the rest of the
kernel.
