Subject: [PATCH 9/8] xfs_io: dedupe command should only complain if we don't dedupe anything
Date: Thu, 4 Oct 2018 15:27:33 -0700	[thread overview]
Message-ID: <20181004222733.GM19324@magnolia> (raw)
In-Reply-To: <153841345236.27952.5050172703525712660.stgit@magnolia>

From: Darrick J. Wong <darrick.wong@oracle.com>

The dedupe command should only complain about non-matching extents if
the kernel hasn't managed to dedupe /any/ of the input range.
