NVMe TP 4053 – Zoned Namespaces (ZNS) allows host software to communicate with a non-volatile memory subsystem using zones for NVMe protocol-based controllers. NVMeOF already support the ZNS NVMe Protocol compliant devices on the target in the passthru mode. There are generic zoned block devices like Shingled Magnetic Recording (SMR) HDDs that are not based on the NVMe protocol. This patch adds ZNS backend support for non-ZNS zoned block devices as NVMeOF targets. This support includes implementing the new command set NVME_CSI_ZNS, adding different command handlers for ZNS command set such as NVMe Identify Controller, NVMe Identify Namespace, NVMe Zone Append, NVMe Zone Management Send and NVMe Zone Management Receive. With the new command set identifier, we also update the target command effects logs to reflect the ZNS compliant commands.
