Are you saying that we need to spread numa_mem_id() all over the place for GFP_THISNODE users on memless nodes? There aren't that many users of GFP_THISNODE. Wouldn't it make far more sense to just change them? Or just introduce a new GFP flag GFP_CLOSE_OR_BUST which allows falling back to the nearest local node for memless nodes. There's no reason to leak this information outside allocator proper.
