From 41cd8b70c37ace40077c8d6ec0b74b983178c192 Mon Sep 17 00:00:00 2001 From: Vishal Verma Date: Thu, 25 Jun 2015 04:21:52 -0400 Subject: libnvdimm, btt: add support for blk integrity Support multiple block sizes (sector + metadata) using the blk integrity framework. This registers a new integrity template that defines the protection information tuple size based on the configured metadata size, and simply acts as a passthrough for protection information generated by another layer. The metadata is written to the storage as-is, and read back with each sector.
