This is precisely why configfs is separate from sysfs. If both
user and kernel can create objects, the lifetime of the object and its
filesystem representation is very complex. Sysfs already has problems
with people getting this wrong. configfs does not.
The fact that sysfs and configfs have similar backing stores
does not make them the same thing.
