Re: [PATCH v2] scsi: lpfc: Add rport validation in lpfc_dev_loss_tmo_callbk

[Justin Tee]

Hi Vaibhav,

1.) This patch looks like it was rebased on top of the first version of 
this patch instead of off the tree.

2.) lpfc_dev_loss_tmo_callbk is the .dev_loss_tmo_callbk routine for 
scsi transport layer to call into our driver when dev_loss_tmo event is 
detected.  A null ndlp->vport in lpfc_dev_loss_tmo_callbk is somewhat 
unexpected.  Rather than checking for a stale pointer, it is more likely 
that an ndlp kref accounting race caused the vport ptr to be freed 
before lpfc_dev_loss_tmo_callbk was called.

Is it possible to share the vmcore’s dmesg.txt file so that we may 
examine the root cause of the stale ndlp->vport ptr?

Regards,
Justin
