From 2341c2f8c33196d02cf5a721746eea4e3c06674a Mon Sep 17 00:00:00 2001 From: "Martin K. Petersen" Date: Fri, 26 Sep 2014 19:20:07 -0400 Subject: block: Add T10 Protection Information functions The T10 Protection Information format is also used by some devices that do not go through the SCSI layer (virtual block devices, NVMe).
