What's going to be done about those patches now? There are two orthogonal problems. One being that the driver advertised conformance to an old SCSI spec. That's being addressed with the separate SPC-3 patch. The other issue is that thin provisioning is being incorrectly advertised. Because that's being addressed by Microsoft and is an isolated use case I'm hesitant to add quirk for it. Whereas I know several other devices that will benefit from the TRY_VPD_PAGES blacklist option. -- Martin K.
