[Hans van Kranenburg <hans@xxxxxxxxxxx>]

I just tagged v11 of the python btrfs library.

https://github.com/knorrie/python-btrfs/

Here's the summary of changes (from CHANGES):

python-btrfs v11, Feb 28, 2019
  * Promote some useful examples to proper programs, and add a man
    page for them. Distro package maintainers can ship these in
    /usr/bin.
    - btrfs-usage-report
    - btrfs-balance-least-used
    - btrfs-space-calculator
    - btrfs-orphan-cleaner-progress
  * Add TEMPORARY_ITEM_KEY and PERSISTENT_ITEM_KEY, which have replaced
    BALANCE_ITEM_KEY and DEV_STATS_KEY in kernel code a while ago.
  * Various small documentation and bug fixes.
