pr_warn_ratelimited() which calls printk_ratelimited(). 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(). */ cheers
