From 1fc7f61c3e604f6bf778b5c6afc2715d79ab7f36 Mon Sep 17 00:00:00 2001 From: Adrien Schildknecht Date: Fri, 20 Feb 2015 03:34:21 +0100 Subject: x86/kernel: Fix output of show_stack_log_lvl() show_stack_log_lvl() does not set the log level after a new line, the following messages printed with pr_cont() are thus assigned to the default log level. This patch prepends the log level to the next message following a new line. print_trace_address() uses printk(log_lvl). Using printk() with just a log level is ignored and thus has no effect on the next pr_cont(). We need to prepend the log level directly into the message.
