Hello Nilesh and Marvell Any chance to get comments/eyes on this please. Given its causing system crashes we need to decide how best to deal with it. QT: Laurence, In understanding the severity, Does end customer uses sg_write_same as the mechanism to move data? Other than the sg_write_same utility, how common is end customer uses 32Byte CDB? It seems like upper layer doesn't have support for 32Bytes CDB at this time. The code path you're modifying is for the T10-PI disk. This disk is "non-T10-PI" where it may create some confusion for next reader n Martin on why we've wander down this code path. Will queue up a patch that plug this hole.
