  These two patches allow userspace to provide an expected diskseq of a
block device and discover when blkback has opened the device.  Together,
these features allow using blkback with delete-on-close block devices,
such as loop devices with autoclear set.

Demi Marie Obenour (2):
  xen-blkback: Implement diskseq checks
  xen-blkback: Inform userspace that device has been opened
