Subject: [f2fs-dev] [PATCH v2 0/1] f2fs-tools: add zone-capacity support
Date: Tue, 21 Jul 2020 22:08:10 +0530 [thread overview]
Message-ID: <20200721163811.18593-1-aravind.ramesh@wdc.com> (raw)
NVM Express Zoned Namespace command set specification allows host software
to communicate with a NVM subsystem using zones. ZNS defines a host-managed
zoned block device model for NVMe devices. It divides the logical address
space of a namespace into zones. Each zone provides a LBA range that shall
be written sequentially. An explicit reset of zone is needed to write to
the zone again.
ZNS defines a per zone capacity which can be equal or less than the
zone-size. Zone-capacity is the number of usable blocks in the zone.
This patchset implements support for ZNS devices with a zone-capacity
that is less that the device zone-size.
Add checks in mkfs and fsck to consider zone-capacity and calculate the
overprovision ratio and free_user_blocks based on the usable segments
in a zone.
