Its filename was mm-init-remove-the-unnecessary-special-treatment-for-memory-less-node-v2.patch This patch was dropped because it was folded into mm-init-remove-the-unnecessary-special-treatment-for-memory-less-node.patch ------------------------------------------------------ From: Baoquan He Subject: mm-init-remove-the-unnecessary-special-treatment-for-memory-less-node-v2 Date: Wed, 10 Apr 2024 11:35:29 +0800 redo code comments, per Mike As Mike suggested, the old code comments above the 'continue' statement is still useful for easier understanding code and system behaviour. So rephrase and move them above line 'if (pgdat->node_present_pages)'. Thanks to Mike.
