From 1e703d0548e0a2766e198c64797737d50349f46e Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Tue, 22 Mar 2022 17:14:21 +0800 Subject: mm/slab: remove some unused functions alternate_node_alloc and ____cache_alloc_node are always called when CONFIG_NUMA. So we can remove the unused !CONFIG_NUMA variant. Also forward declaration for alternate_node_alloc is unnecessary. Remove it too.
