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:
