Hi Mathias,
I don't think there is active work on this.
Additionally to the issues you mentioned above, stat() returns device IDs
for BTRFS subvolumes and BTRFS snapshots which are different from the parent
BTRFS mount point; e.g. also 'find -fstype btrfs' chokes on this [1].

Therefore, I'm still using EXT4 and XFS on my SLES12 systems.
Have a nice day,
Berny
