 	ignore_loglevel	[KNL]
 			Ignore loglevel setting - this will print /all/
 			kernel messages to the console. Useful for debugging.
+			We also add it as printk module parameter, so users
+			could change it dynamically, usually by
+			/sys/module/printk/parameters/ignore_loglevel.
 
 	ihash_entries=	[KNL]
