Re: [PATCH] scsi: lpfc: Fix potential deadlock on &phba->hbalock

Hi Justin,

Thanks much for the reply,  it is my negligence of not have noticed it,
and sorry for this.

I inspect the bug report of my tool again and just find that actually
lpfc_sli4_intr_handler() also acquires that lock.

lpfc_sli4_intr_handler()
    -> lpfc_sli4_hba_intr_handler()
    -> spin_lock_irqsave(&phba->hbalock, iflag);

It seems like this isr is called on an SLI4 type HBA. If consider this
one could it be a deadlock problem?

Thanks again,
Chengfeng
