[libvirt] [PATCH] Fix bug in storage driver accessing wrong private data

Looks correct - ACK. This fixes the crash in libvirtd? Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones New in Fedora 11: Fedora Windows cross-compiler.

Yes, it may or may not crash depending mostly on luck. It didn't crash for me, but it certainly wouldn't give the answer you'd want :-) Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|

ah, it's conn->storagePrivateData instead of conn->privateData, I initially got confused why the argument rename would fix something... ACK !
