Commit e61734c55c24 ("cgroup: remove cgroup->name") added two extra
newlines to memcg oom kill log messages. This makes dmesg hard to read
and parse. The issue affects 3.15+.
Example:
Task in /t <<< extra #1
killed as a result of limit of /t
<<< extra #2
memory: usage 102400kB, limit 102400kB, failcnt 274712
Remove the extra newlines from memcg oom kill messages, so the messages
look like:
Task in /t killed as a result of limit of /t
memory: usage 102400kB, limit 102400kB, failcnt 240649
Fixes: e61734c55c24 ("cgroup: remove cgroup->name")
