From b257bc051f06607beb3004d9a1c297085e728bec Mon Sep 17 00:00:00 2001 From: Andrew Johnson Date: Fri, 16 Mar 2007 13:38:24 -0800 Subject: [PATCH] swsusp: fix suspend when console is in VT_AUTO+KD_GRAPHICS mode When the console is in VT_AUTO+KD_GRAPHICS mode, switching to the SUSPEND_CONSOLE fails, resulting in vt_waitactive() waiting indefinitely or until the task is interrupted. This patch tests if a console switch can occur in set_console() and returns early if a console switch is not possible.
