--- Comment #2 from Chris Wilson <chris at chris-wilson.co.uk> ---
The complaint is that it saw a dirty page... But all dirt should have been
flushed by the invalidate/truncate itself.

One possibility is that the rcu fput() is racing against shmemfs activity...
Except we fput after we teardown the pages on freeing the object -- there
should not be a race!
