From 24b4b67d17c308aaa956b73ab1e88190f6642bbe Mon Sep 17 00:00:00 2001 From: Samo Pogacnik Date: Wed, 25 Aug 2010 20:44:07 +0200 Subject: add ttyprintk driver Ttyprintk is a pseudo TTY driver, which allows users to make printk messages, via output to ttyprintk device. It is possible to store "console" messages inline with kernel messages for better analyses of the boot process, for example.
