Its filename was mm-sparse-rename-and-cleanup-sparse_init_nid.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 ------------------------------------------------------ From: "David Hildenbrand (Arm)" Subject: mm/sparse: rename and cleanup sparse_init_nid() Date: Mon, 21 Sep 2026 21:58:56 +0200 Let's rename it to "sparse_metadata_init_nid", avoid the "pnum" terminology and drop the function comment. Further, rename the "map" variable to "mem_map" for consistency with other functions.
