[libvirt] [PATCH] virDrvStorageVolLookupByKey and virDrvStorageVolLookupByPath should use virStoragePoolPtr as parameter



Hello,

These two functions, virDrvStorageVolLookupByKey and virDrvStorageVolLookupByPath should use virStoragePoolPtr as parameter instead of virConnectPtr for some few reasons:

1) Should follow the standard virStorage*Ptr parameters like the rest of storage related functions.

2) Functions now are able to access pool structure. This is particularly important for the optimization of the PowerHypervisor phypVolumeLookupByKey function.

Thanks,
