Subject: [RFC v2 5/6] mptsas: use async probe
Date: Thu, 4 Sep 2014 23:37:26 -0700 [thread overview]
Message-ID: <1409899047-13045-6-git-send-email-mcgrof@do-not-panic.com> (raw)
In-Reply-To: <1409899047-13045-1-git-send-email-mcgrof@do-not-panic.com>
From: "Luis R. Rodriguez" <mcgrof@suse.com>
Its reported that mptsas can at times take over 30 seconds
to recognize SCSI storage devices [0], this is done on the
driver's probe path. Use the the new asynch probe to
circumvent systemd from killing this driver.
