Subject: [PATCH 06/13] btrfs: introduce BTRFS_FEATURE_INCOMPAT_SPARE_DEV
Date: Tue, 10 May 2016 22:09:25 +0800 [thread overview]
Message-ID: <1462889372-5274-8-git-send-email-anand.jain@oracle.com> (raw)
In-Reply-To: <1462889372-5274-1-git-send-email-anand.jain@oracle.com>
From: Anand Jain <Anand.Jain@oracle.com>
Add BTRFS_FEATURE_INCOMPAT_SPARE_DEV (400) flag to identify
a spare device.
Along with this it checks in the mount context that a spare
device will fail to mount. As spare devices aren't mountable.
