From 4e7392ec582cf06753b0969ca9ab959923e38493 Mon Sep 17 00:00:00 2001 From: "Martin K. Petersen" Date: Sun, 20 Sep 2009 16:49:38 -0400 Subject: [SCSI] sd: Support disks formatted with DIF Type 2 Disks formatted with DIF Type 2 reject READ/WRITE 6/10/12/16 commands when protection is enabled. Only the 32-byte variants are supported. Implement support for issusing 32-byte READ/WRITE and enable Type 2 drives in the protection type detection logic. Signed-off-by: Martin K.
