I did think again and do not see a way how the life cycle problems can
be solved while drivers happily access the device struct of the adapter.
Whatever the solution to the core problem is (revocable, custom SRCU,
something else), I still think this step is needed in any case. If I am
wrong with this opinion, please enlighten me. Pointer to some existing
thread is OK, too. I didn't have the bandwidth to read the revocable
mail threads.
Happy hacking,
Wolfram
