Re: [libvirt] [PATCH] storage: util: Properly ignore errors when backing volume is inaccessible

Commit 000e9504559 tried to fix improper bracketing when refreshing disk volume stats for a backing volume. Unfortunately the condition is still wrong as in cases as the backing store being inaccessible storageBackendUpdateVolTargetInfo returns -2 if instructed to ignore errors. The condition does not take this into account. Dumping XML of a volume which has inacessible backing store would then result into: # virsh vol-dumpxml http.img --pool default error: An error occurred, but the cause is unknown Properly ignore -2 for backing volumes.
