    [SCSI] Handle MLQUEUE busy response in scsi_send_eh_cmnd · fc73648a
    Hannes Reinecke authored
    scsi_send_eh_cmnd() is calling queuecommand() directly, so
    it needs to check the return value here.
    The only valid return codes for queuecommand() are 'busy'
    states, so we need to wait for a bit to allow the LLDD
    to recover.
    
    Based on an earlier patch from Wen Xiong.
    
    [jejb: fix confusion between msec and jiffies values and other issues]
