[libvirt] [PATCH 26/38] virlog: Swap the new copy of outputs with the global existing one
Actually perform the swap between the active set of outputs and the
user-provided copy. Deallocation ensures that no file descriptors that should
not have been closed are not closed and all descriptors that should be closed
are closed properly.
