Hello James Smart,

This is a semi-automatic email about new static checker warnings.

The patch cb69f7decc37: "[SCSI] lpfc 8.3.28: Add support for ABTS 
failure handling" from Dec 13, 2011, leads to the following Smatch 
complaint:

drivers/scsi/lpfc/lpfc_sli.c +8391 lpfc_sli4_abts_err_handler()
	 error: we previously assumed 'ndlp' could be null (see line 8387)

drivers/scsi/lpfc/lpfc_sli.c
  8386	
  8387		if (!ndlp || !NLP_CHK_NODE_ACT(ndlp))
                    ^^^^^
New check.

  8388			lpfc_printf_log(phba, KERN_INFO, LOG_SLI,
  8389					"3115 Node Context not found, driver "
  8390					"ignoring abts err event\n");
  8391		vport = ndlp->vport;
                        ^^^^^^^^^^^
New dereference.  Maybe the intent was to return after the print
statement?

  8392		lpfc_printf_log(phba, KERN_WARNING, LOG_SLI,
  8393				"3116 Port generated FCP XRI ABORT event on "

regards,
dan carpenter

Dan,

We should have another patch set coming shortly - will address it in that patch.
