The four values in printk denote:
- console_loglevel - messages with a priority higher than this will be printed to the console
- default_message_loglevel - messages without an explicit priority will be printed with this priority
- minimum_console_loglevel - minimum (highest) value to which console_loglevel can be set
- default_console_loglevel - default value for console_loglevel
These values influence printk() behavior when printing or logging error messages. See syslog(2) for more info on the different loglevels.
