Subject: [PATCH 25/29] xfs_repair: collect relatime reverse-mapping data for refcount/rmap tree rebuilding
Date: Thu, 25 Aug 2016 17:01:20 -0700	[thread overview]
Message-ID: <147216968057.7022.6386690839466970601.stgit@birch.djwong.org> (raw)
In-Reply-To: <147216950911.7022.438115723996286926.stgit@birch.djwong.org>

Collect reverse-mapping data for realtime files so that we can later
check and rebuild the reference count tree and the reverse mapping
tree.
