The quilt patch titled
     Subject: mm/numa: remove unnecessary local variable in alloc_node_data()

     mm-numa-remove-unnecessary-local-variable-in-alloc_node_data.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/numa: remove unnecessary local variable in alloc_node_data()
Date: Sun, 27 Apr 2025 18:04:42 +0800

The temporary local variable 'nd' is redundant.  Directly assign the
virtual address to node_data[nid] to simplify the code.

No functional change.
