[libvirt] [PATCH 13/20] test: Convert testDriver to virObjectLockable
Marc Hartmayer
mhartmay at linux.vnet.ibm.com
Thu Mar 8 12:20:36 UTC 2018
The test driver state (@testDriver) uses it's own reference counting
and locking implementation. Instead of doing that, convert @testDriver
into a virObjectLockable and use the provided functionalities.
