Subject: [PATCH 04/19] xfs: introduce realtime rmap btree definitions
Date: Thu, 31 Aug 2017 13:33:49 -0700	[thread overview]
Message-ID: <150421162950.17458.13956738145194349139.stgit@magnolia> (raw)
In-Reply-To: <150421160433.17458.10817316901867396010.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.
