<pre>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!</pre>
