The virNetDevGenerateName() function uses a global array of virNetDevGenName structs to find next unused name for network device. This obviously needs some locking and in fact each member of the array has its own lock. However, these members are not virObjects, they are just plain structs, therefore VIR_WITH_MUTEX_LOCK_GUARD() must be used instead of VIR_WITH_OBJECT_LOCK_GUARD() to lock individual mutexes.
