From: Tom Yan <[email protected]> Some devices have details of their support on unmapping on the Block Limits and/or Logical Block Provisioning VPDs while they do not set the LBPME bit to 1. Though this is required by the SCSI standards, the VPDs are giving even more concrete details about the support, so they should be used even when the bit is set to 0.
