blk-mq: remove the calling of local_memory_node()
We don't need to check whether the node is memoryless numa node before calling allocator interface. SLUB(and SLAB,SLOB) relies on the page allocator to pick a node. Page allocator should deal with memoryless nodes just fine. It has zonelists constructed for each possible nodes. And it will automatically fall back into a node which is closest to the requested node. As long as __GFP_THISNODE is not enforced of course. The code comments of kmem_cache_alloc_node() of SLAB also showed this: * Fallback to other node is possible if __GFP_THISNODE is not set. blk-mq code doesn't set __GFP_THISNODE, so we can remove the calling of local_memory_node().
