--- Comment #4 from Michal Kubeček ---
I couldn't see any obvious problem in the module source, neither have I any
idea what kind of change could result in such refcounting problem. Some tips
for debugging:
1. Seeing how does the refcount behave might give us some hint. Try e.g. to
display the refcount repeatedly after loading the module to see if it's
growing,
decreasing or stays the same (in the third case, it would be interesting to see
how the values differ in repeated tests).
2. There are tracepoints module:module_get and module:module_point so that
you could use perf to trace refcount changes. If there is a misbalance in get
and put operations, it could tell us where.
