Re: [libvirt] [PATCH 1/2] resize: add virStorageVolResize() API

From: "Zeeshan Ali (Khattak)" <zeeshanak(a)gnome.org&gt; Add a new function to allow changing of capacity of storage volumes. Plan out several flags, even if not all of them will be implemented up front. Expose the new command via 'virsh vol-resize'.
