Please don't add errors on mem alloc failures. They just bloat the kernel, there will be a rather large OOM splat in the logs if GFP_KERNEL allocation fails.

• pool->gen_pool->name = pool_name;

If you add the new allocation after this line, I think you wouldn't have to free pool_name under the if () explicitly.
