procfs should be okay. sysfs was too intertwined with driver model and
module reference counting never worked well. We had to pull module
reference counting out of there.

No, I don't think so. The code won't go away beneath it. After
module_put() the module can die (ie. calling __module_get() on it will
trigger BUG) but it won't go away till the function finishes.
