Title:
  Failure to remove kernel partition mappings in yakkety
  (2.28.1-1ubuntu1)

Status in util-linux package in Ubuntu:
  Confirmed

Bug description:
  In the move from 2.28-5ubuntu2 and 2.28.1-1ubuntu1 of util-linux we
  see a regression when asking kpartx to remove kernel partition
  mappings where the appear to remain.

  Context: We create and modify disk images heavily.  The example
  recreate creates a 2GB disk image with a single partition.  From that
  2GB image we will resize it to 8GB and grow the partition/filesystem.
  This stopped working in yakkety with 2.28.1-1ubuntu1.

  We do have a work-around which is call growpart on the file rather on
  the loopback device.

  Recreate script is attached.
