Subject: [PATCH 1/3] mm/page_alloc: Add an alloc_pages_bulk_array_node() helper
Date: Sun, 16 May 2021 22:20:54 +0200 [thread overview]
Message-ID: <20210516202056.2120-2-urezki@gmail.com> (raw)
In-Reply-To: <20210516202056.2120-1-urezki@gmail.com>
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.
