I tested with kernels 4.6.3 and 4.7-rc5 and with btrfs-progs 4.5.2 and
4.61. The later kernel with two patches to make the kernel work:
https://lkml.org/lkml/2016/6/1/310 https://lkml.org/lkml/2016/6/1/311 .

You can see the script¹ I used (do-btrfs-du-test) and the logs at
http://m-berberich.de/btrfs/

In all four cases, ‘btrfs fi du -s .’ reports

     Total   Exclusive  Set shared  Filename
  59.38MiB       0.00B    29.69MiB  .

befor balance and

     Total   Exclusive  Set shared  Filename
  59.38MiB    59.38MiB       0.00B  .

after balance.
