[Andrew Morton]

The quilt patch titled
     Subject: selftests/vm: drop mnt point for hugetlb in run_vmtests.sh
has been removed from the -mm tree.  Its filename was
     selftests-vm-drop-mnt-point-for-hugetlb-in-run_vmtestssh.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: selftests/vm: drop mnt point for hugetlb in run_vmtests.sh
Date: Fri, 14 Oct 2022 10:40:15 -0400

After converting all the three relevant testcases (uffd, madvise, mremap)
to use memfd, no test will need the hugetlb mount point anymore.  Drop the
code.
