Yes, i made tests with  this one :

			ITERATE_RDEV(mddev,rdev,rtmp) {
				if (!mddev) {
					printk(KERN_INFO "md: *****BUG***mddev***********!!!\n");
					break;
				}
				printk(KERN_INFO "md: *****mddev=%p rdev=%p *************!!!\n", 
mddev, rdev);
				if (!rdev) {
					printk(KERN_INFO "md: *****BUG**rdev*************!!!\n");
					break;
				}
				if (rdev->raid_disk < 0
				    && !rdev->faulty) {
					if (mddev->pers->hot_add_disk(mddev,rdev))
						spares++;
					else {
						printk(KERN_INFO "********break\n");
						break;
					}
				}
				printk(KERN_INFO "md: *****test2************!!!\n");
}

And ******test2 wasn't reached, nor *****break.
I have a lot of printks outside of this loop, never reached too
