[libvirt] [PATCH RFC 7/9] volume: Convert virStorageVolObj[List] to use virPoolObj[Table]
John Ferlan
jferlan at redhat.com
Sat Feb 11 16:29:43 UTC 2017
Use the virPoolObj[Table] object management model in order to manage the
storage volume objects.
While making the adjustments to use the new model, there are some code
formatting adjustments that were also made with the goal to follow more
recent code flow and layout.
