Thu Jul 19 16:40:47 UTC 2012
The RPC generator doesn't returning support list of object, this
patch do the work manually.
* daemon/remote.c:
Implemente the server side handler remoteDispatchStoragePoolListAllVolumes
* src/remote/remote_driver.c:
Add remote driver handler remoteStoragePoolListAllVolumes
* src/remote/remote_protocol.x:
New RPC procedure REMOTE_PROC_STORAGE_POOL_LIST_ALL_VOLUMES and
structs to represent the args and ret for it.
* src/remote_protocol-structs: Likewise.
