Subject: [PATCH 15/21] xfs: dynamically create the realtime rmapbt inode when attaching rtdev
Date: Tue, 31 Dec 2019 17:17:53 -0800	[thread overview]
Message-ID: <157784147380.1368137.15826925395082289505.stgit@magnolia> (raw)
In-Reply-To: <157784137939.1368137.1149711841610071256.stgit@magnolia>

From: Darrick J. Wong <darrick.wong@oracle.com>

If the administrator asks us to add a realtime volume to an existing
rmap filesystem, we must allocate and attach the rtrmapbt inode to the
system prior to enabling the rt volume.
