[libvirt] [PATCH 03/15] conf: Introduce VIR_DEFINE_AUTOPTR_FUNC for virStorageVolDef

John Ferlan jferlan at redhat.com
Wed Feb 6 13:41:35 UTC 2019


Let's make use of the auto __cleanup capabilities cleaning up any
now unnecessary goto paths. For virStorageVolDefParseXML use the
@def/@ret similarly as other methods.
