The quilt patch titled
     Subject: mm/hugetlb: assert hugetlb_lock in __hugetlb_cgroup_commit_charge
has been removed from the -mm tree.  Its filename was
     mm-hugetlb-assert-hugetlb_lock-in-__hugetlb_cgroup_commit_charge.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

Date: Wed, 17 Apr 2024 17:18:36 -0400

This is similar to __hugetlb_cgroup_uncharge_folio() where it relies on
holding hugetlb_lock.  Add the similar assertion like the other one, since
it looks like such things may help some day.
