[PATCH] swsusp: Use suspend_console
Add suspend_console() and resume_console() to the suspend-to-disk code paths so that the users of netconsole can use swsusp with it. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Pavel Machek <pavel@ucw.cz> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
