Subject: [PATCH 28/76] xfs: piggyback rmapbt update intents in the bmap free structure
Date: Sat, 19 Dec 2015 00:59:25 -0800	[thread overview]
Message-ID: <20151219085925.12713.15426.stgit@birch.djwong.org> (raw)
In-Reply-To: <20151219085622.12713.88678.stgit@birch.djwong.org>

Extend the xfs_bmap_free structure to track a list of rmapbt update
intents.  In a subsequent patch, we'll defer all data fork rmapbt
edits until we're done making changes to the bmbt, at which point we
can replay the rmap edits in order of increasing AG number.  This
enables us to avoid deadlocks by complying with AG lock ordering
rules.
