Subject: [PATCH 14/16] scsi_dh: invoke callback if ->activate is not present
Date: Fri, 20 Dec 2013 13:13:39 +0100 [thread overview]
Message-ID: <1387541621-54967-15-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1387541621-54967-1-git-send-email-hare@suse.de>
When ->activate isn't present we still need to invoke the
callbacks, otherwise the system might stall.
