NAME
       console_unlock - unlock the console system

SYNOPSIS
       void console_unlock(void);

ARGUMENTS
       void
	   no arguments

DESCRIPTION
       Releases the console_lock which the caller holds on the console system and the console driver list.

       While the console_lock was held, console output may have been buffered by printk. If this is the case, console_unlock; emits the output
       prior to releasing the lock.

       If there is output waiting, we wake /dev/kmsg and syslog users.

       console_unlock; may be called from any context.
