[libvirt] [PATCH 0/5] snapshots: topological sorting (incremental backup saga)

While working to add new API for bulk dumpxml/redefine, and turn
virDomainSnapshotObjList into a base class for sharing with
checkpoints, I realized how trivial it would be to take advantage of
information already present on the server, instead of using a lot of
CPU time with 'virsh snapshot-list --tree' to reconstruct a DAG on
the client side.

Eric Blake (5):
  snapshots: Add flag to guarantee topological sort
  snapshots: Support topological visits
  test: Support topological visits
  qemu: Support topological visits
  virsh: Add snapshot-list --topological
