Subject: [PATCH v8 02/41] btrfs: introduce ZONED feature flag
Date: Fri, 2 Oct 2020 03:36:09 +0900 [thread overview]
Message-ID: <778806c32892a82a27a9252f8d33003fa95a20ee.1601574234.git.naohiro.aota@wdc.com> (raw)
In-Reply-To: <dece91bca322ce44bed19f2b0f460fa5ded2e512.1601574234.git.naohiro.aota@wdc.com>
This patch introduces the ZONED incompat flag. The flag indicates that the
volume management will satisfy the constraints imposed by host-managed
zoned block devices.
