John Ogness 9023ca0866 printk: do not wait for consoles when suspended ... The console_stop() and console_start() functions call pr_flush(). When suspending, these functions are called by the serial subsystem while the serial port is suspended. In this scenario, if there are any pending messages, a call to pr_flush() will always result in a timeout because the serial port cannot make forward progress. This causes longer suspend and resume times. Add a check in pr_flush() so that it will immediately timeout if the consoles are suspended. Fixes: 3b604ca812 ("printk: add pr_flush()") Reported-by: Todd Brandt <todd.e.brandt@linux.intel.com> Signed-off-by: John Ogness <john.ogness@linutronix.de> Tested-by: Todd Brandt <todd.e.brandt@linux.intel.com> Signed-off-by: Petr Mladek <pmladek@suse.com> Link: https://lore.kernel.org/r/20220715061042.373640-2-john.ogness@linutronix.de		2022-07-15 10:52:11 +02:00
