other info that might help us debug this:

Chain exists of:
  event_mutex --> &dup_mmap_sem --> &mm->mmap_sem

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&mm->mmap_sem);
                               lock(&dup_mmap_sem);
                               lock(&mm->mmap_sem);
  lock(event_mutex);
