[PATCH V3 4/9] nvmet: add NVME_CSI_ZNS in ns-desc for zbdev

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

 



When discovering the ZNS, the host-side looks for the NVME_CSI_ZNS
value in the ns-desc. Update the nvmet_execute_identify_desclist()
such that it can now update the ns-desc with NVME_CSI_ZNS if bdev is
zoned.
