    Subject[RFC v2 5/6] mptsas: use async probe
    Date
    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.
