Subject: [PATCH 1/4] block: Remove annoying "unknown partition table" message

    As Christoph put it:
      Can we just get rid of the warnings?  It's fairly annoying as devices
      without partitions are perfectly fine and very useful.

    Me too I see this message every VM boot for ages on all my
    devices. Would love to just remove it. For me a partition-table
    is only needed for a booting BIOS, grub, and stuff.
