[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Keith Busch <kbusch@xxxxxxxxxx>

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. 

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.

  null_blk: introduce zone capacity for zoned device
