So you just pointed to *another* data structure that apparently violates
the "you MUST use refcounting" rule.
What is it with you people? It's really simple. Data structures must be
refcounted if you can reach them two different ways.
If you don't use refcounting, then you'd better make sure that the data
can be reached only one way (for example, by *not* exposing it for sysfs).
It really *is* that simple. Read the CodingStyle rules.
