From cfe36bde59bc1ae868e775ad82386c3acaabb738 Mon Sep 17 00:00:00 2001 From: Diego Calleja Date: Wed, 14 Nov 2007 16:58:54 -0800 Subject: [PATCH] Improve cgroup printks When I boot with the 'quiet' parameter, I see on the screen: [ 0.000000] Initializing cgroup subsys cpuset [ 0.000000] Initializing cgroup subsys cpu [ 39.036026] Initializing cgroup subsys cpuacct [ 39.036080] Initializing cgroup subsys debug [ 39.036118] Initializing cgroup subsys ns This patch lowers the priority of those messages, adds a "cgroup: " prefix to another couple of printks and kills the useless reference to the source file.
