[libvirt] [PATCH 06/11] Separate internal node suspend APIs from public API

Thu May 2 12:03:44 UTC 2013


From: "Daniel P. Berrange" <berrange at redhat.com>

The individual hypervisor drivers were directly referencing
APIs in virnodesuspend.c in their virDriverPtr struct. Separate
these methods, so there is always a wrapper in the hypervisor
driver. This allows the unused virConnectPtr args to be removed
from the virnodesuspend.c file. Again this will ensure that
ACL checks will only be performed on invocations that are
directly associated with public API usage.
