From d8a5dc3033af2fd6d16030d2ee4fbd073460fe54 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Fri, 7 Feb 2014 11:38:30 +0100 Subject: tty: Set correct tty name in 'active' sysfs attribute The 'active' sysfs attribute should refer to the currently active tty devices the console is running on, not the currently active console. The console structure doesn't refer to any device in sysfs, only the tty the console is running on has. So we need to print out the tty names in 'active', not the console names. This resolves an issue on s390 platforms in determining the correct console device to use.
