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 diff --git a/src/lpfc-12.2.0.0/lpfc_scsi.c b/src/lpfc-12.2.0.0/lpfc_scsi.c index 3f1375a..19c8505 100644 --- a/src/lpfc-12.2.0.0/lpfc_scsi.c +++ b/src/lpfc-12.2.0.0/lpfc_scsi.c
