[PATCH 1/1] Drivers: scsi: storvsc: Add blist flags

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add blist flags to permit the reading of the VPD pages even when
the target may claim SPC-2 compliance. MSFT targets currently
claim SPC-2 compliance while they implement post SPC-2 features.
With this patch we can correctly handle WRITE_SAME_16 issues.
