Description

NVMe 1.1. will support namespaces that have an 64bit Extended Unique Identifier (EUI64), which will allow to identify namespaces on dual-ported or dual-hosted controllers. To support that in the nvme driver blkdev needs to support that as well.

A blkdev driver such as nvme should be able to report the EUI64 to blkdev, and blkdev should use it as target number in the device nodes similar to how SAS/FC WWNs are handled.
