From: Miaohe Lin Date: Tue, 22 Mar 2022 09:14:21 +0000 (+0800) Subject: mm/slab: remove some unused functions X-Git-Tag: v5.19-rc1~166^2~10 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1e703d0548e0a2766e198c64797737d50349f46e;p=thirdparty%2Flinux.git 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.
