Subject: [PATCH 16/18] xfs: refactor reflink flag handling in xfs_swap_extent_forks
Date: Tue, 28 Apr 2020 19:45:59 -0700 [thread overview]
Message-ID: <158812835926.168506.1546972667821869337.stgit@magnolia> (raw)
In-Reply-To: <158812825316.168506.932540609191384366.stgit@magnolia>
From: Darrick J. Wong <darrick.wong@oracle.com>
Refactor the old data fork swap function to use the new reflink flag
helpers to propagate reflink flags between the two files.
