Subject: btrfs-progs (4.4.1-1.1) unstable; urgency=medium

  * Non-maintainer upload.
  * New upstream release.
  * Rename package to btrfs-progs (Closes: #780081)
  * Update standards version to 3.9.7 (no changes needed).
  * debian/control: Add "Breaks" per Gianfranco Costamagna's suggestion
  * Change lintian override to reflect package rename
  * Switch from using postinst and postrm to using triggers
    per Christian Seiler's recommendation.
