[libvirt] what ever happened to the SCSI HBA storage backend?

Hi Folks - I see Daniel Berrange submitted a SCSI HBA storage backend in March. What ever happened to that? I'd be happy to pick this up if there's more work to do (is there a code base later than the posted patch?) In the longer run, I'm looking towards adding support necessary for FC environments (like multipath). Also, it seems (to my iSCSI-ignorant mind) that iSCSI should be just another flavor of the SCSI driver (kind of like netfs is a flavor of the fs driver ...). Is anyone working on such a refactoring? Thanks, Dave
