Title:
  [utopic] btrfs: label should not contain return char

Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Utopic:
  Fix Committed

Bug description:
  SRU Justification:

  [Impact]
  Minor impact: It is possible to introduce a newline into the btrfs label output from the btrfs sys file /sys/fs/btrfs/$UUID/label, this newline should be filtered out.

  [Fix]
  clean upstream cherry pick 48fcc3ff7dce0138c053833adf81670494f177f3 "btrfs: label should not contain return char".

  [Testcase]
  The commit contains a suitable testcase, see below:

  TEST_DEV=/dev/vdb
  TEST_DIR=/home/sat/mnt

  umount /home/sat/mnt

  mkfs.btrfs -f $TEST_DEV
  UUID=$(btrfs fi show $TEST_DEV | head -1 | sed -e 's/.*uuid: \([-0-9a-z]*\)$/\1/')
  mount $TEST_DEV $TEST_DIR
  LABELFILE=/sys/fs/btrfs/$UUID/label

  echo "Test for empty label..." >&2
  LINES="$(cat $LABELFILE | wc -l | awk '{print $1}')"
  RET=0

  if [ $LINES -eq 0 ] ; then
      echo '[PASS] Trailing \n is removed correctly.' >&2
  else
      echo '[FAIL] Trailing \n still exists.' >&2
      RET=1
  fi

  echo "Test for non-empty label..." >&2

  echo testlabel >$LABELFILE
  LINES="$(cat $LABELFILE | wc -l | awk '{print $1}')"

  if [ $LINES -eq 1 ] ; then
      echo '[PASS] Trailing \n is removed correctly.' >&2
  else
      echo '[FAIL] Trailing \n still exists.' >&2
      RET=1
  fi

  exit $RET

  This is to be SRU'd for utopic only, trusty does not have this
  interface supported and this fix is carried in vivid.
