Subject: [PATCH 06/26] libmultipath: use 'is_daemon' as argument for domap() etc
Date: Mon,  4 Jul 2016 09:08:26 +0200	[thread overview]
Message-ID: <1467616126-10036-7-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1467616126-10036-1-git-send-email-hare@suse.de>

Use 'is_daemon' as argument for domap() and coalesce_paths()
to avoid having to access struct config.
