The device stats can be read by ioctl, wrapped by command 'btrfs device
stats'. Provide another source where to read the information in
/sys/fs/btrfs/FSID/devinfo/DEVID/stats .

  The planned stat here is errors stat.
  So why not rename this to error_stats?

I think it's commonly called device stats, dev stats, so when it's in
'devinfo' it's like it's the 'stats' for the device. We don't have other
stats, like regarding io but in that case it would make sense to
distnguish the names.
