The quilt patch titled
     Subject: mm: hugetlb: convert to account_new_hugetlb_folio()
has been removed from the -mm tree.  Its filename was
     mm-hugetlb-convert-to-account_new_hugetlb_folio.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: hugetlb: convert to account_new_hugetlb_folio()
Date: Wed, 10 Sep 2025 21:39:55 +0800

In order to avoid the wrong nid passed into the account, and we did make
such mistake before, so it's better to move folio_nid() into
account_new_hugetlb_folio().
