If you want this then you also need to align struct kmem_cache. internode aligned would require the kmem_cache to be page aligned. So lets drop the hunk from this patch for now. A separate patch may convince us to merge aligning kmem_cache_node within kmem_cache. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
