Perhaps names like foo_bar_baz_dev_warn are a bit long.

Maybe instead of
+	(?:[a-z0-9]+_)+(?:printk|emerg|alert|crit|err|warning|warn|notice|info|debug|dbg|vdbg|devel|cont|WARN)(?:_ratelimited|_once|)|
use
+	(?:[a-z0-9]+_){0,2}(?:printk|emerg|alert|crit|err|warning|warn|notice|info|debug|dbg|vdbg|devel|cont|WARN)(?:_ratelimited|_once|)|
