  hyper-v: Unable to take backups of Generation 2 VMs

Status in “linux” package in Ubuntu:
  Fix Committed
Status in “linux” source package in Trusty:
  Fix Committed

Bug description:
  We are unable to take backups of Generation 2 VMs because they include
  a FAT 32 EFI partition. This patch ignores such partitions while
  freezing the file-system to take a snapshot during the initial stages
  of the backup process. Since EFI partition is not expected to be
  modified regularly, the ignore functionality should address the
  problem. Please include the following upstream patch in the vss

  Tools: hv: vssdaemon: Ignore VFAT mounts during the Freeze operation
  If the guest has a FAT file system mounted, skip it during the FREEZE
  operation. With this change we can support host initiated backup of
  the guest even when the guest may have FAT file systems mounted.
