Yes, good catch; lpfc does. For v5 there's a new patch ahead of this one that has lpfc_rx_monitor_report() print each record with seq_buf_printf() and, when one doesn't fit, end the string where it began, so its debugfs output still stops at the last whole record. I've checked all the other users of seq_buf_puts() and didn't find any other cases like this. -Kees -- Kees Cook
