--- Comment #2 from Matthew L. Martin <mlmartin@...arsky-data.com> ---
I believe that I have confirmed that this fault is not present in linux 4.7.
After running the reproduction script for over three hours I have not seen a
difference between the usage reported by du and df:

# df -h /mnt/hdd_sd[gh]; du -hs  /mnt/hdd_sd[gh]
Filesystem      Size  Used Avail Use% Mounted on
/dev/sdg        5.5T   20G  5.4T   1% /mnt/hdd_sdg
/dev/sdh        5.5T   20G  5.4T   1% /mnt/hdd_sdh
20G    /mnt/hdd_sdg
20G    /mnt/hdd_sdh
