Hi Miles.

Good idea, perhaps less good an implementation though.

This should be a change on the line above like

	printk(?:_ratelimited|_once|_deferred|_deferred_once|)|

without a change on your suggested line.

Or perhaps changing both lines if there are to be
macros/functions like pr_<level>_deferred_once someday.

  	printk(?:_ratelimited|_once|_deferred|_deferred_once|)|
	(?:[a-z0-9]+_){1,2}(?:printk|emerg|alert|crit|err|warning|warn|notice|info|debug|dbg|vdbg|devel|cont|WARN)(?:_ratelimited|_once|_deferred|deferred_once|)|
