Marcus Sorensen commented on CLOUDSTACK-7315:
---------------------------------------------
I haven't been paying a ton of attention to the list, admittedly, but I think
it would be good to use caution when changing signatures of functions. This
commit breaks storage plugins (adaptors) for KVM. We will want to notify Mike
and whoever else may have implemented a Storage Adaptor.
