[PATCH V2 5/9] nvmet: add cns-cs-ctrl in id-ctrl for ZNS bdev

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

 



Update the nvmet_execute_identify() such that it can now handle
NVME_ID_CNS_CS_CTRL when identify.cis is set to ZNS. This allows
host to identify the support for ZNS.
