[dm-devel] [PATCH v2 02/21] multipathd: avoid sending "READY=1" to systemd on early shutdown

[mwilck at suse.com]

From: Martin Wilck <mwilck at suse.com>

If multipathd gets a shutdown request during initial reconfigure(),
it shouldn't send "READY=1" to systemd. Ensure this by sending
"READY=1" via post_config_state().
