Subject: [PATCH 1/2] drivers/base/memory: add node id parameter to add_memory_block()
Date: Tue,  1 Jul 2025 13:41:53 +0200	[thread overview]
Message-ID: <20250701114155.16452-2-hare@kernel.org> (raw)
In-Reply-To: <20250701114155.16452-1-hare@kernel.org>

Add a 'nid' parameter to add_memory_block() to initialize the memory
block with the correct node id.
