Subject: [PATCH 55/63] xfs: convert unwritten status of reverse mappings for shared files
Date: Thu, 29 Sep 2016 20:11:37 -0700	[thread overview]
Message-ID: <147520509794.29434.12442767454067687441.stgit@birch.djwong.org> (raw)
In-Reply-To: <147520472904.29434.15518629624221621056.stgit@birch.djwong.org>

Provide a function to convert an unwritten extent to a real one and
vice versa when shared extents are possible.

Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com>

v2: Move rmap unwritten bit to rm_offset.
