Subject: [PATCH 40/71] xfs: convert unwritten status of shared-extent reverse mappings on shared files
Date: Thu, 25 Aug 2016 16:50:51 -0700	[thread overview]
Message-ID: <147216905121.4420.12444976161755026169.stgit@birch.djwong.org> (raw)
In-Reply-To: <147216879156.4420.2446767701729565218.stgit@birch.djwong.org>

Upgrade the rmap extent conversion function to handle shared extents.

v2: Move unwritten bit to rm_offset.
