Perhaps a per instance use instead. Something like:

#define printk_ratelimited(fmt, arg...) \
({ static struct ratelimit_state _rs = { \
.interval = DEFAULT_RATELIMIT_INTERVAL, \
.burst = DEFAULT_RATELIMIT_BURST, \
}; \
int rtn; \
\
if (!__ratelimit(&_rs)) \
rtn = printk(fmt, ##arg); \
else \
rtn = 0; \
rtn; \
})
#define pr_info_rl(fmt, arg) \
printk_ratelimited(KERN_INFO pr_fmt(fmt), ##arg)
etc...
