This is an appliance that has its own "kernel".
Code:
Linux nas-B9-43-AA 4.1.21.x86_64.1

but under the hood it's:
Code:
root@nas-B9-43-AA:/# cat /etc/*release
PRETTY_NAME="ReadyNASOS 6.5.1"
NAME="Debian GNU/Linux"
VERSION_ID="7"
VERSION="7 (wheezy)"

Hi,
Instead of going to the dentry - inode - superblock - device id.
I get the device Id using the getattr(..) on the dentry.

My solution is taken from the Suse patch in the subject (after alot of google digging).

btrfs: stat(2) and /proc/pid/maps returns different devices - Patchwork
