Yes the goal is for it staying around forever, correct. And ->fasync()
will go instead.

Advantage is that out of tree drivers will be compile broken which I
consider an advantage. Yes I know Linus said earlier that's not
important to him, but in this case my standards are higher than his.

Also BTW if you're that worried about the audit not getting
finished then the result would be just that lots of lock_kernel()s
would stay around. Hardly better.

But cannot do that many drivers in one step.

My goal is to just audit the remaining ones and then remove ->fasync()
and unlocked_fasync stays. Will be hopefully not that far away, since
fasync is relatively easy. The conversions are mostly for me to keep
track which ones I audited.
