Its filename was mm-hugetlb_vmemmap-move-alloc_vmemmap_page_list-next-to-its-free-helper.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: Muchun Song Subject: mm: hugetlb_vmemmap: move alloc_vmemmap_page_list() next to its free helper Date: Wed, 04 Nov 2026 10:35:06 +0800 Keep alloc_vmemmap_page_list() together with free_vmemmap_page_list(). This also allows the folio-oriented optimization helper introduced in a subsequent change to reuse the allocator without a forward declaration. No functional change intended.
