From 497957576cf8a2150d723aedd74ea60b5d498bfe Mon Sep 17 00:00:00 2001 From: Petr Mladek Date: Mon, 12 Dec 2016 16:45:47 -0800 Subject: printk/kdb: handle more message headers Commit 4bcc595ccd80 ("printk: reinstate KERN_CONT for printing continuation lines") allows to define more message headers for a single message. The motivation is that continuous lines might get mixed. Therefore it make sense to define the right log level for every piece of a cont line. This patch introduces printk_skip_headers() that will skip all headers and uses it in the kdb code instead of printk_skip_level(). This approach helps to fix other printk_skip_level() users independently.
