No it shouldn't. Please refer to https://lkml.org/lkml/2012/3/7/242
The intent here was just to match slub's printout for its slab_out_of_memory node list slab components, as one can check on mm/slub.c:
2096 printk(KERN_WARNING 2097 " node %d: slabs: %ld, objs: %ld, free: %ld\n", 2098 node, nr_slabs, nr_objs, nr_free);
