Subject: [PATCH v6 01/28] btrfs: introduce HMZONED feature flag
Date: Fri, 13 Dec 2019 13:08:48 +0900 [thread overview]
Message-ID: <20191213040915.3502922-2-naohiro.aota@wdc.com> (raw)
In-Reply-To: <20191213040915.3502922-1-naohiro.aota@wdc.com>
This patch introduces the HMZONED incompat flag. The flag indicates that
the volume management will satisfy the constraints imposed by host-managed
zoned block devices.
