Title:
  [SRU] exfat not detected by blkid

Status in util-linux package in Ubuntu:
  Fix Released
Status in util-linux source package in Trusty:
  Invalid
Status in util-linux source package in Utopic:
  In Progress

Bug description:
  [Impact]

  Due to a upstream bug blkid is unable to detect exfat partitions. This
  breaks proper detection and automount of exfat formatted partitions
  (e.g. SD cards or USB sticks)  in Ubuntu 14.10.

  [Test Case]

  Insert an exfat formatted SD Card (card is neither detected nor automounted)
  or
  run as root: blkid [partition]

  Without the fix:
  sudo blkid -p /dev/sde1
  /dev/sde1: ambivalent result (probably more filesystems on the device, use wipefs(8) to see more details)

  With the fix applied:
  sudo blkid -p /dev/sde1
  /dev/sde1: UUID="BE12-8543" VERSION="1.0" TYPE="exfat" USAGE="filesystem" PTTYPE="dos" PART_ENTRY_SCHEME="dos" PART_ENTRY_TYPE="0x7" PART_ENTRY_FLAGS="0x80" PART_ENTRY_NUMBER="1" PART_ENTRY_OFFSET="32768" PART_ENTRY_SIZE="124702720" PART_ENTRY_DISK="8:64" 

  [Regression Potential]

  None known, the bugfix is simple and part of already released upstream
  stable release (2.25.2).
