[PATCH v3 0/4] block/scsi/nvme: Add error codes for PR ops

[Martin K. Petersen]

Mike,

> The following patches were made over Linus's tree and allow the
> PR/pr_ops users to handle errors without having to know the device
> type and also for SCSI handle devices that require the sense
> code. Currently, we return a -Exyz type of error code if the PR call
> fails before the drivers can send the command and a device specific
> error code if it's queued. The problem is that the callers don't
> always know the device type so they can't check for specific errors
> like reservation conflicts, or transport errors or invalid operations.
>
> These patches add common error codes which callers can check for.

This looks OK to me. Not sure which tree makes the most sense to funnel
this through?
