Subject: [PATCH v2 07/21] multipathd: set_config_state(): avoid code duplication
Date: Thu, 24 Sep 2020 15:37:02 +0200	[thread overview]
Message-ID: <20200924133716.14120-8-mwilck@suse.com> (raw)
In-Reply-To: <20200924133716.14120-1-mwilck@suse.com>

From: Martin Wilck <mwilck@suse.com>

Use __post_config_state() and __wait_for_state_change(). This
way __post_config_state() is the only place where running_state
is ever changed, and we avoid code duplication.
