Subject: Improve cgroup printks
From: Diego Calleja <diegocg@xxxxxxxxx>
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.
