My guess is that you only want one vnode for each 'entity'.
However for kernfs does it matter if each lookup actually
references a 'clone' of the entity.

This would be not dissimilar to having a directory full of
lots of copies of (say) boottime, and each caller being given
a separate one.

OTOH kernfs could just sit on a vnode for each entry!
Until it contains a driver generated device tree this
won't matter.
