Subject: Re: [PATCH 1/5] block: add capacity field to zone descriptors
Date: Tue, 16 Jun 2020 11:41:21 -0400 [thread overview]
Message-ID: <yq1sgevm31m.fsf@ca-mkp.ca.oracle.com> (raw)
In-Reply-To: <20200615233424.13458-2-keith.busch@wdc.com> (Keith Busch's message of "Tue, 16 Jun 2020 08:34:20 +0900")
Keith,
> In the zoned storage model, the sectors within a zone are typically
> all writeable. With the introduction of the Zoned Namespace (ZNS)
> Command Set in the NVM Express organization, the model was extended to
> have a specific writeable capacity.
>
> Extend the zone descriptor data structure with a zone capacity field to
> indicate to the user how many sectors in a zone are writeable.
>
> Introduce backward compatibility in the zone report ioctl by extending
> the zone report header data structure with a flags field to indicate if
> the capacity field is available.
