Message-Id: <1406031230-18107-2-git-send-email-elder@linaro.org> Date: Tue, 22 Jul 2014 07:13:44 -0500 From: Alex Elder <elder@...aro.org> To: akpm@...ux-foundation.org Cc: kay@...y.org, pmladek@...e.cz, bp@...e.de, john.stultz@...aro.org, jack@...e.cz, linux-kernel@...r.kernel.org Subject: [PATCH v6 1/7] printk: report dropped messages on separate line It is possible for the log to be filled too quickly for the consoles to be able to keep up. This is detected in console_unlock(), and when it occurs, a message is inserted to note the event. When reviewing some nearby code, Petr Mládek suggested it might be nicer if this message were placed on a separate line. This patch implements that suggestion.
