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. [ vbabka@suse.cz: move ____cache_alloc_node() declaration closer to its callers ] Signed-off-by: Miaohe Lin <linmiaohe@huawei.com> Reviewed-by: David Hildenbrand <david@redhat.com> Reviewed-by: Roman Gushchin <roman.gushchin@linux.dev> Signed-off-by: Vlastimil Babka <vbabka@suse.cz> Link: https://lore.kernel.org/r/20220322091421.25285-1-linmiaohe@huawei.com
