[PATCH v2 0/7] NVMe Data Integrity Extensions

[Keith Busch]

This patch set adds data integrity extensions to NVMe. Contrast with
the previous patch attempt, this makes some modifications to sd_dif
to export the template so a block driver can make use of it instead of
copying it. There are more namespace block formats possible than what is
available in SCSI, so I had to make some modifications to the integrity
code to take this into account. I hope that's okay.

Keith Busch (7):
  sd: remove invalid ref tag check
  sd: skip verifying unwritten sectors
  sd: hw sector size calculation
  sd: arbitrary dif meta-data sizes
  sd: export dif integrity template
  NVMe: Split non-mergeable bio requests
  NVMe: End-to-end data protection
