Subject: [PATCH v5 01/28] btrfs: introduce HMZONED feature flag
Date: Wed,  4 Dec 2019 17:17:08 +0900	[thread overview]
Message-ID: <20191204081735.852438-2-naohiro.aota@wdc.com> (raw)
In-Reply-To: <20191204081735.852438-1-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.
