Subject: [PATCH 09/21] xfs: add a realtime flag to the rmap update log redo items
Date: Tue, 31 Dec 2019 17:17:16 -0800	[thread overview]
Message-ID: <157784143622.1368137.8626042257765831402.stgit@magnolia> (raw)
In-Reply-To: <157784137939.1368137.1149711841610071256.stgit@magnolia>

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

Extend the rmap update (RUI) log items with a new realtime flag that
indicates that the updates apply against the realtime rmapbt.  We'll
wire up the actual rmap code later.
