[PATCH 3/4] conf: Convert virDomainChrSourceDefNew to return object

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Let's use object referencing to handle the ChrSourceDef. A subsequent
patch then can allow the monConfig to take an extra reference before
dropping the domain lock to then ensure nothing free's the memory that
needs to be used.
