Add blist flags to permit the reading of the VPD pages even when
the target may claim SPC-2 compliance. MSFT targets currently

I don't really understand this disk cache thing.
Suppose a disk with write cache enabled of writeback type: Linux
receives a write completed notification (a message from the disk) when
the data has reached the cache of the disk. Correct? At that point it is
