[PATCH 1/1] first line in booting the kernel

[PATCH 1/1] first line in booting the kernel

[Alexandru GOIA]

What it does : first line of booting kernel, as seen in dmesg(1), will be the Linux kernel signature
(version, compiler, compiler hostname).

What it solves : it appers ahead of cgroup messages at booting.


So, instead of the unaesthetic lines :

Initializing cgroup subsys cpuset
Initializing cgroup subsys cpu
Initializing cgroup subsys cpuacct
Linux version 4 ....

... We will have :

Linux version 4 ...
Initializing cgroup subsys cpuset
Initializing cgroup subsys cpu
Initializing cgroup subsys cpuacct

As normal .

(And I guess we need your sign-off, and probably Cc:
trivial@kernel.org).
