 Note, be careful with st_dev, because:

    * after 
            mount --bind /mnt/A /mnt/A

      /mnt/A has the same devno as /mnt/A/B, but /mnt/A is a mountpoint 

    * btrfs returns different st_dev for different subvolumes within the
      same filesystem and the numbers don't match with the maj:min
      numbers from /proc/self/mountinfo (in the file is used only
      devno for entire FS).
