I like how slub handles this when it can't allocate more slab with slab_out_of_memory() and has the added benefit of still warning even with __GFP_NORETRY that the oom killer is never called for. If there's really a slab leak happening, there's a good chance that this diagnostic information is going to be emitted by the offending cache at some point in time if you're using slub. This could easily be extended to slab.c, so it's even more reason not to include this type of information in the oom killer.
