# HG changeset patch
# User root@xxxxxxxxxxxxxxxxxxxxx
# Date 1291305003 18000
# Node ID 15700c869b5445ce6d239513c54d6f69f9d62808
# Parent 2e6a1485047a2e91c2e90d8ffdbf6c9a9814588c
HACK/PoC: adjust for minor differences in upstream Xc bindings
Just a PoC at this stage. It might be better to push the interface differences
to xen-api-libs.hg now to reduce the churn when rebasing to 4.1
