Perhaps you missed pr_warn_ratelimit() macro which is already in the
kernel for a long time.

pr_warn_ratelimited() which calls printk_ratelimited().

I stand corrected.
Right, that's what I had in mind (actually didn't know that there are variants).

Thanks!

And see the comment above printk_ratelimit():

/*
 * Please don't use printk_ratelimit(), because it shares ratelimiting state
 * with all other unrelated printk_ratelimit() callsites.  Instead use
 * printk_ratelimited() or plain old __ratelimit().
