The quilt patch titled
Subject: mm/vma: drop incorrect comment from vms_gather_munmap_vmas()
has been removed from the -mm tree. Its filename was
mm-vma-drop-incorrect-comment-from-vms_gather_munmap_vmas.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/vma: drop incorrect comment from vms_gather_munmap_vmas()
Date: Fri, 30 Aug 2024 00:01:00 -0400
The comment has been outdated since 6b73cff239e52 ("mm: change munmap
splitting order and move_vma()"). The move_vma() was altered to fix the
fragile state of the accounting since then.
