Date: Tue, 16 Sep 2014 16:42:52 +0200 From: Markus Trippelsdorf <markus@...ppelsdorf.de> To: Jan Kara <jack@...e.cz> Cc: Geert Uytterhoeven <geert@...ux-m68k.org>, "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org>, Steven Rostedt <rostedt@...dmis.org>, Andrew Morton <akpm@...ux-foundation.org> Subject: [PATCH] printk: git rid of [sched_delayed] message for printk_deferred commit 458df9fd hardcodes printk_deferred() to KERN_WARNING and inserts the string "[sched_delayed] " before the actual message. However it doesn't take into account the KERN_* prefix of the message, that now ends up in the middle of the output: [sched_delayed] ^a4CE: hpet increased min_delta_ns to 20115 nsec Fix this by just getting rid of the "[sched_delayed] " scnprintf().
