[libvirt] PATCH: 3/12: Re-factor storage backend integration
Daniel P. Berrange

Thu Nov 13 17:23:05 UTC 2008
My previous patch for refactoring the storage backends broke the test
driver's storage capabilities. The problem was that it made the backends
private to the storage driver, but part of them was in fact needed by
the XML parsers. This patch pulls a bunch of code out of the storage_backenmd
file, and individual drivers and puts it straight into storage_conf.c/h
for generic use by the parser. The storage backends are not totally
private to the storage driver, and the test driver's storage impl still
works
