It might've helped if Rusty had actually used our
scripts/get_maintainer.pl script to CC people. While Anthony seems to
have reviewed some patches (usually Reviewed-by should be before the
final Signed-off-by fwiw), neither Stefan (virtio-net) nor Kevin
(virtio-blk) nor Paolo (virtio-scsi) were CC'ed, and recently Michael
stepped up as virtio maintainer, so maybe he can take them once ready.
1/7 looks okay to me; 3-7 are rather mechanical - people will need to
review that those changes are sufficient for the current code base.
We've since converted virtio devices to QOM realize, so a rebase is
likely needed for such an "old" series.

Andreas
