From: "Uladzislau Rezki (Sony)" <urezki@xxxxxxxxx>
Subject: mm/page_alloc: add an alloc_pages_bulk_array_node() helper
Patch series "vmalloc() vs bulk allocator", v2.
This patch (of 3):
Add a "node" variant of the alloc_pages_bulk_array() function. The helper
guarantees that a __alloc_pages_bulk() is invoked with a valid NUMA node
ID.
