Subject: [PATCH 04/21] xfs: introduce realtime rmap btree definitions
Date: Tue, 31 Dec 2019 17:16:45 -0800	[thread overview]
Message-ID: <157784140499.1368137.8959307371819498135.stgit@magnolia> (raw)
In-Reply-To: <157784137939.1368137.1149711841610071256.stgit@magnolia>

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

Add new realtime rmap btree definitions. The realtime rmap btree will
be rooted from a hidden inode, but has its own shape and therefore
needs to have most of its own separate types.
