Subject: [PATCH v5 11/22] multipath -u: common code path for result message
Date: Sat, 14 Apr 2018 00:00:04 +0200	[thread overview]
Message-ID: <20180413220015.7032-12-mwilck@suse.com> (raw)
In-Reply-To: <20180413220015.7032-1-mwilck@suse.com>

Print the result message in one place only. This simplifies
future changes. multipath -c is also affected.
