Did you have something specific in mind? I am not sure it's worth it,
really.
The kmalloc_large() function is a static inline in
include/linux/slub_def.h that gets inlined nicely to a get_order() +
__get_free_pages() pair in the caller for production configs. I'm not
sure what we should print either. There's no known "object size" or
"buffer size" nor do we any of the variable order things or backing
struct kmem_cache_nodes.
