v2->v3:

  Added warnings for unsupported ZNS drives (Klaus)

  Fixed double newline

  Added reviews

Background:

The NVM Express workgroup has ratified technical proposals enabling new
command sets. The specifications may be viewed from the following link:

  https://nvmexpress.org/wp-content/uploads/NVM-Express-1.4-Ratified-TPs.zip

This series implements support for the Zoned Namespace (ZNS) Command Set
defined in TP4053, and the Namespace Types base support it depends on
from TP4056. As this series depends on the block layer's append support
infrastructure, append-capable ZNS devices are required for this patch
sets enabling.

The block layer is updated to include the new zone writeable capacity
feature from ZNS, and existing zone block device drivers are updated to
incorporate this feature.
