Re: [libvirt] [PATCH v2 4/6] vol: Add thin_pool to _virStorageVolSource

A thin lv doesn't have any extents defined - rather it uses a concept of a "thin-pool" in order to describe it's source. In order to allow that to be displayed properly in a future patch, add a new 'thin_pool' name that can be used by a future patch to store the name of the source thin_pool name used by a thin logical volume.
