The patch also saves us some additional memory on !PRINTK configs.
For example things like this
if (kobj->state_initialized) {
/* do not error out as sometimes we can recover */
printk(KERN_ERR "kobject (%p): tried to init an initialized "
"object, something is seriously wrong.\n", kobj);
dump_stack();
}
now we won't have that dump_stack() call, which does not seems to be doing
anything useful anyway when printk() is not available.
