+                        [KNL] Change console messages format
+                default
+                        By default we print messages on consoles in
+                        "[time stamp] text\n" format (time stamp may not be
+                        printed, depending on CONFIG_PRINTK_TIME or
+                        `printk_time' param).
+                syslog
+                        Switch to syslog format: "<%u>[time stamp] text\n"
+                        IOW, each message will have a facility and loglevel
+                        prefix. The format is similar to one used by syslog()
+                        syscall, or to executing "dmesg -S --raw" or to reading
+                        from /proc/kmsg.
