Subject: [PATCH 6/9] nvmet: add cns-cs-ns in id-ctrl for ZNS bdev
Date: Wed, 25 Nov 2020 18:40:40 -0800	[thread overview]
Message-ID: <20201126024043.3392-7-chaitanya.kulkarni@wdc.com> (raw)
In-Reply-To: <20201126024043.3392-1-chaitanya.kulkarni@wdc.com>

Update the nvmet_execute_identify() such that it can now handle
NVME_ID_CNS_CS_NS when identify.cis is set to ZNS. This allows
host to identify the ns with ZNS capabilities.
