From fffb906532d6f1c6c486706da0b8b08a3e70b0fd Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Sun, 17 Nov 2013 22:25:02 +0100 Subject: [PATCH] drm: Don't split up debug output Otherwise we risk that the 2nd part of the line ends up on a line of it's own, which means a kernel dmesg line without a log level. This then upsets the dmesg checker in piglit. Only really happens in some of the truly nasty igt testcases which race cache dropping (through debugfs) with other gem operations.
