[libvirt] [PATCH 07/10] Turn some dual-state int parameters into booleans
Daniel P. Berrange
berrange at redhat.com
Tue Nov 27 18:18:17 UTC 2012
From: "Daniel P. Berrange" <berrange at redhat.com>
The virStateInitialize method and several cgroups methods were
using an 'int privileged' parameter or similar for dual-state
values. These are better represented with the bool type.
Signed-off-by: Daniel P. Berrange <berrange at redhat.com>
