Hi everyone
Please refer to the latest patch.
There is a race deadlock in the function lpfc_abort_handler
potential deadlocks arising from lock ordering problems.
It’s the correct order
spin_unlock(&lpfc_cmd->buf_lock)
spin_unlock_irqrestore(&phba->hbalock, flags);
How to solve it ? I think that the patch is reasonable,
can you help me review and commit this patch, Best regards

We confirmed the issue you stated. We are looking at what you proposed
and will be adding a patch that will be posted in our next
