Cover letter [PATCH 0/2] Add Opal unlock support to NVMe.

This patch series implement a small set of the Opal protocol for self encrypting devices. It's implemented only what is needed for saving a password and unlocking a given "locking range". The password is saved on the driver and replayed back to the device on resume from suspend to RAM. It is specifically supporting the single user mode.

It is not planned to implement the full Opal protocol (at least not for now).
I think the OPAL code should be a generic library outside the NVMe code so that we can use it for SATA and SAS as well, just with a little glue code for the Security Send / Receive commands to wire it up to NVMe.
Fully agree. Having generic OPAL support would be a major benefit.
Cheers,
Hannes
