Its filename was mm-sparse-vmemmap-open-code-vmemmap_populate_address.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: Muchun Song Subject: mm/sparse-vmemmap: open-code vmemmap_populate_address() Date: Tue, 29 Sep 2026 13:32:30 +0800 vmemmap_populate_address() no longer has any callers that need the returned PTE. Its only remaining user, vmemmap_populate_range(), only checks whether population succeeded. Open-code vmemmap_populate_address() directly in vmemmap_populate_basepages(), remove the now-redundant range helper, and return -ENOMEM directly on failure.
