From fcae695737fca0849c18db814d9d8de05c0fd2a2 Mon Sep 17 00:00:00 2001 From: Vishal Verma Date: Thu, 25 Jun 2015 04:22:39 -0400 Subject: libnvdimm, blk: add support for blk integrity Support multiple block sizes (sector + metadata) for nd_blk in the same way as done for the BTT. Add the idea of an 'internal' lbasize, which is properly aligned and padded, and store metadata in this space.
