I apparently missed the issue and designed the interface without considering this ugliness. Maybe kernfs could be made to wrap rather than providing mount/kill_sb() functions and hide details about sb or we can simply add fstype->umount() so that there's symmetry; however, the problem is kernfs-specific and other kernfs users would have single static backing store and won't need to care about this, so, for now, I think what it's a ugly but acceptable compromise.
