Title:
  [Precise] btrfs-tools much too old for kernel features

Status in “btrfs-tools” package in Ubuntu:
  New

Bug description:
  The btrfs-tools package that comes with precise is
  0.19+20100601-3ubuntu3, (2010 !) which, given the pace of BTRFS
  development, is much older than the current BTRFS version that the
  kernel supports.

  This results in several issues among which :

  - Unable to convert back to ext4 a filesystem that has been converted
  from ext4 to BTRFS then mounted (btrfs-convert -r will state the
  volume has unsupported features, and then segfault)

  - btrfsck is unusable : will state the volume has unsupported
  features, and then segfault.

  Please update the btrfs-tools package to a decently recent version,
  corresponding to the BRFS features that the kernel actually
  implements.
