If the hardware is not support some error reporting, it need direct report this information to user who use aer_inject userspace tool. He need change the his inject configuration file, rather than kernel report him successful inject AER but no any useful information at console or dmesg output. Anyway, In my mind, it should not be very important issue to stop this patch go to mainline.
