Sorry for jumping in late. But I just see this today and I really like the
idea to add a switch to turn off the kmsg writing from userspace because
I suffer from it also.

I may missed the background, what is the reason for "ratelimit"? It sounds
a little odd. I think use default "on" should be safe to keep same behavior
as before.
