Strictly speaking, this is not fully true. "max_reason" field is not ignored when set to KMSG_DUMP_PANIC even when always_kmsg_dump was not set. It should be something like: "which gets ignored for reason higher than KMSG_DUMP_OOPS unless always_kmsg_dump is passed as kernel parameter". Heh, I wonder if anyone will be able to parse this ;-) Otherwise, it looks good to me. With the updated commit message: Reviewed-by: Petr Mladek <pmladek@xxxxxxxx> Best Regards, Petr
