Subject: [PATCH v14 06/42] btrfs: do not load fs_info->zoned from incompat flag
Date: Tue, 26 Jan 2021 11:24:44 +0900	[thread overview]
Message-ID: <a5df66e698c59ab058cece26456520d882d2f4be.1611627788.git.naohiro.aota@wdc.com> (raw)
In-Reply-To: <cover.1611627788.git.naohiro.aota@wdc.com>

From: Johannes Thumshirn <johannes.thumshirn@wdc.com>

Don't set the zoned flag in fs_info when encountering the
BTRFS_FEATURE_INCOMPAT_ZONED on mount. The zoned flag in fs_info is in a
union together with the zone_size, so setting it too early will result in
setting an incorrect zone_size as well.

Once the correct zone_size is read from the device, we can rely on the
zoned flag in fs_info as well to determine if the filesystem is running in
zoned mode.
