other info that might help us debug this:

Chain exists of:
  sb_internal#4 --> &ei->i_mmap_lock --> btrfs_ordered_extent

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  rlock(btrfs_ordered_extent);
                               lock(&ei->i_mmap_lock);
                               lock(btrfs_ordered_extent);
  rlock(sb_internal#4);
